Location:

If replacing an old thermostat, the new thermostat will be mounted in place of the old. If a new location is desired, it will be necessary to move your wiring. New installations and relocation should follow the guidelines below to ensure the most accurate temperature reading and ease of use.

• Mount the thermostat on an inside wall, approximately 5 ft. (1.5m) above the floor in a frequently used room.
• Do not install in locations near appliances or devices that affect the local temperature, such as televisions, lamps, or dryers.
• Avoid areas that are exposed to large temperature variances, such as: direct sunlight, near an AC unit, above or below auxiliary heat and air vents, and drafts from windows.
• Be aware of what is on the other side of the wall that the thermostat is being installed on. Do not install on walls adjacent to unheated rooms, stoves, or housing hot water pipes.
• Damp areas will not only affect the humidity reading of your thermostat, but could also lead to corrosion, shortening the life of your thermostat.
• Install in a location with good air circulation. Stagnant air will not accurately reflect the rate of change of temperature in the room. Avoid areas behind open doors, corners, and alcoves.
• Wait until construction and painting are finished before installing.

Removing Existing Thermostat:

Test your system

• Verify that your heating and/or cooling system is operating properly before you try to install your new thermostat.
• DO NOT do so by shorting (jumper) across electric terminals at the furnace or air conditioner. This may damage the thermostat.

Warning: DO NOT REMOVE your existing thermostat until power has been turned off at the circuit breaker.

Once power to the heating AND cooling systems is off, follow these steps:

• Remove the cover from your existing thermostat. Do not disconnect the wires yet.
  TIP: Take a picture of the wires before you detach them from the existing thermostat.
• Label all existing wires, one at a time, with the labels provided.

Removing Existing Thermostat:

• Disconnect all of the wires and remove the existing thermostat.
  TIP: Remember to secure the wires so they don’t fall into the wall.

CAUTION: Wiring can vary for each manufacturer. Label all wiring before removing it from your existing thermostat.

What wires does your system use?

Make sure your wires are labeled correctly. It may be necessary to find the ‘other end’ connection for each wire on your heating or air conditioning equipment and read the label there.

IMPORTANT: This thermostat runs on batteries and the C wire. If you do not have a C wire, you can run a new wire from the HVAC or use a standard 24VAC wall transformer

Prepare the wires

Please follow these guidelines for safe and secure wire connections:

• Ensure the wires are the proper gauge.
• Make sure wires have exposed straight ends about 1/8” long.

CAUTION: Verify that your system is 24 VAC. If your old system is labeled as 120 or 240 volts, or has wire nuts, your system is high voltage. Do not install your thermostat to a high-voltage system. Contact your local HVAC professional for help.

Install Your New Thermostat

Install the back plate

Use the bubble level provided on the back plate as a guide. Mark where the screws will go with a pencil through the screw holes on the back plate.

TIPS:

• Use the trim plate to cover up any marks or holes left from the old thermostat. Attach the trim plate before securing the back plate to the wall.
• Drill holes with a 3/16” drill bit to tap in the drywall anchors for added support.

Wire your new thermostat

Go to page 8 to find the wiring diagram that matches your wiring and insert the wires into the back plate.

TIP: Anything that wasn’t connected to your old thermostat shouldn’t be connected to your new thermostat either. You may also have extra wires that do not match. Leave them as is.

EXCEPTIONS:

• If you have R, connect it to RH.
• If you have RH & RC, remove the black jumper in the lower left corner of back plate terminal board.
• Z can be used for W3, H, or DH.

Wiring Diagrams:

Insert batteries into the thermostat body

The thermostat can be powered by a battery or 24 VAC. If a wall transformer is used to power your thermostat, connect between C and RH. Ensure the batteries are installed following the specified polarity markings on the thermostat.

CAUTION: Special Battery Warning

• Always replace the batteries as soon as the ” Low Battery ” indicator is indicated. If the batteries die, your thermostat could leave the HVAC system on, overheating or freezing your home.
• Always replace the batteries at least once a year. This will protect your thermostat from damage and corrosion by leaking batteries.
• If your home is unoccupied for a month or more, such as vacation homes, you should replace the batteries as a preventive measure against battery failure while you are away.
• Use only new batteries when changing.

Connect the Thermostat to the Gateway

• Bring Gateway to the Thermostat.
• Put the thermostat in OFF mode (No mode icons are lit).
• Press the inclusion button on the Gateway.
• Press and hold the DOWN button the thermostat to begin pairing. The RADIO icon should start blinking.
• When the RADIO icon becomes solid, the thermostat is joined to the network.
• Log in to your account to sync your thermostat with the Building 36 system, or contact your local professional for installation setup.

Install the thermostat body to the back plate

Press the thermostat body firmly into the back plate mounted to the wall. Ensure that the pins on the body are correctly aligned with the header attached to the terminal board on the back plate. Failure to do so could cause damage to the thermostat.

Turn the power on

Restore power to your heating and cooling system. This can be done at the circuit breaker.

Configure Your System

Your thermostat configuration will be done online at the customer site on your customer account page. Here you will configure the parameters of your system, such as: Heat Pump or Normal, number of heat and cool stages, heating fuel, calibration temperature, and configurable terminal (Z). Refer to your configuration number on the wiring diagrams page to see the values you should enter on the online configuration.
This is also where you have the option to change advanced configuration settings, such as: Swing, Differential, Recovery Setting, Fan Circulation Period and Duty Cycle, Maximum Setpoints, Minimum Setpoints, Thermostat Lock, Demand Response Delay, Demand Response Duty Cycle, and Modes Enabled.

WARNING: Use caution when changing advanced configuration settings. These configuration settings should only be changed by those familiar with heating and cooling systems’ parameters. Contact your local HVAC professional for help. For definitions of these settings and more information, go to www.building36.com

Check Your System

By default, the thermostat is configured to 2 heat stages and 2 cool stages (2 Heat Pump, 2 Aux).

To check heating

Press the MODE button to select HEAT mode.

• Press the UP button to raise the setpoint above room temperature.
• Wait 10 seconds for the system to turn on.
• After verifying the heating system is working, raise the setpoint to the desired temperature.

To check the cooling

Press the MODE button to select COOL mode.

• Press the DOWN button to lower the setpoint below room temperature.
• Wait 10 seconds for the system to turn on.
• After verifying the cooling system is working, lower the setpoint to the desired temperature.

Troubleshooting

Batteries die quickly

If a thermostat is paired using a C-Wire, that information is saved in the network and cannot be changed unless removed and paired again without a C-Wire connected. The same applies to inclusions on battery power. If you find your thermostat batteries are dying unusually quickly, check and make sure the C-Wire connection is still intact. If a device is paired using C-Wire, the Z-Wave communication never sleeps, and the thermostat will act as a repeater, sending messages for other devices as well. If the C-Wire is removed, this kind of activity will drain the battery very quickly.

Heating or cooling doesn’t turn on when the target is set above or below the ambient temperature

The thermostat is configured to have a minimum setting of a half-degree difference in temperature from the target before the system turns on to protect the system from damage due to excessive use. The cooling system also has a built-in compressor delay. Each time the compressor is turned on, a large amount of pressure is built up and must be equalized. This delay time prevents damage to the compressor from not allowing this pressure to equalize before being turned on again.

Manual configuration of the HVAC system on thermostat

The system type (Normal or Heat Pump) can be physically set on the thermostat if necessary by doing the following:

1. Put the thermostat in OFF mode.
2. Press and hold the UP button.
3. Press UP or DOWN buttons to select either ‘HP’ for heat pump configuration or ‘NORM’ for normal configuration.
4. Press the MODE button to confirm your selection.

Exclusion of the thermostat from the Z-Wave network

If, for some reason, the thermostat must be removed from the network, follow the steps below to do so.

1. Press and hold the exclusion button on the gateway.
2. Press and hold the DOWN button on the thermostat to enter exclusion mode. The RADIO icon will begin flashing red.
3. When the RADIO icon becomes solid, the thermostat has now been successfully removed from the network.

The heat pump is cooling when it should be heating

Because both types of heat pump reversing valves share a single terminal on your thermostat back plate, you need to be sure you have the thermostat configured for the correct wire. Try switching your O/B selection on the customer thermostat configuration page. Contact your local HVAC professional for further assistance with this issue. The same applies to a heat pump that is heating when it should be cooling.
