INSTALLATION CONSIDERATIONS

Power

This Thermostat is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low‐ voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections.

Rh and Rc are connected via the shunt jumper (see Fig. 1). For applicaƟons using two 24VAC transformers, one in the indoor unit and one in the outdoor unit, remove the shunt jumper (Fig. 1). Connect the common from each to the C terminal. Connect R from the indoor unit to the Rh terminal. Connect R from the outdoor unit to the Rc terminal. The W signals are taken from the Rh power and the Y signal is taken from the Rc power. If Thermostat has been installed in a two—transformer application that is later changed to a single—transformer installation, installer must install a field supplied jumper between Rc and Rh.

Fig. 1 – Shunt Jumper

Accessory Output and Connections

This thermostat is equipped with a dry contact output for the management of humidifiers, dehumidifiers and ventilation equipment. The 2 terminals are both labeled as ACC. The dry contact output must be configured for the management of either one of them.

Ventilation/ERV/HRV

Function will be activated for the % on time configured, using a cycle rate of 1h. For example, if it is set to 50%, function will be active for the first 30min and inactive for the next 30min. If the difference in temperature is larger than the defined max indoor/outdoor temp delta, the function will never activate. If the outdoor temperature is not available, the thermostat will still follow the percent on time, disregarding the max delta parameter.

Humidifier

Control will be based on a setpoint (which will trigger the activation of the function) and a pre‐defined hysteresis of 5% above the setpoint. If humidifier with active heat option is selected, the humidifier will only be activated when the heat is running, regardless of the humidifier setpoint.

Dehumidifier

Control will be based on a setpoint (which will trigger the activation of the function) and a hardcoded hysteresis of 5% below the setpoint. If dehumidifier with fan opƟon is selected, the dehumidifier will only be activated when the fan is running, regardless of the dehumidifier setpoint.

INSTALLATION

⚠ CAUTION

UNIT DAMAGE HAZARD

Failure to follow the recommended wiring practices could result in damage to the wall control and personal property. Improper wiring or installation may damage the thermostat. Check to make sure wiring is correct before proceeding with installation or turning on power.

SYSTEM START‐UP AND CHECKOUT

The Thermostat is designed with a built‐in installer test capability, Output Test Mode. This allows for easy operaƟon of equipment without delays or setpoint adjustments to force heaƟng or cooling. To use this feature you must first configure the thermostats HVAC type via Manual Setup of Thermostat HVAC ConfiguraƟon on the Thermostat or via the installer mobile app.

To enable and use installer Output Test Mode take the following steps:

1. Hold the Mode key for 10 seconds (only works if system is configured).

2. Once Output Test Mode is entered the Thermostat will display S0.

3. When in the Output Test Mode:

a. Use the Mode buƩon to go back.

b. Use the Fan buƩon to select.

c. Use Up and Down buƩons to cycle through opƟons.

4. Stages or Modes available for test are dependent on the HVAC configuraƟon which has been setup. Only those applicable to the selected HVAC type will be shown. The supported test types are as follows:

a. Test Heat Stage 1 (H1)

b. Test Heat Stage 2 (H2)

c. Test Auxiliary Heat Stage 1 (A1)

d. Test Auxiliary Heat Stage 2 (A2)

e. Test Cool Stage 1 (C1)

While testing the appropriate mode icon and perimeter lighting will blink until test has finished or is stopped.

OPERATIONAL INFORMATION

User Interface

The display is a dead front display. All digits, icons, and perimeter lighting will be off unless the proximity sensor is activated, a key is pressed by the user, or unless a heating or cooling call occurs. The first key touch will be ignored if the display was off unless the thermostat had already been woken up by the proximity sensor. Once the display has been woken up the ambient temperature will be shown on the segmented display. The up and down temperature arrows, the applicable mode and fan icons, the Wi‐Fi on or off icon and Open ADR (if active) will light up.

Timers

Five‐‐Minute Compressor Time guard

This timer prevents compressor from starting unless it has been off for at least 5 minutes. Cycle Timer

To prevent short cycling of the HVAC system, especially in the case where compressors are involved, the number of cycles per hour will be limited. This will be a settable parameter through the HVAC configuration in the App. Heating and cooling cycles will be set independently.

For heating the following minimum run time (MRT) and minimum off time (MOT) defaults will be applied based on the number of cycles per hour:

Standard Gas – MRT = 7, MOT = 5 (5 Cycles per hour)
Standard Elec – MRT = 5, MOT = 3 (7.5 Cycles per hour)
Heat pump – MRT = 15, MOT = 5 (3 Cycles per hour)

For cooling, the following MRT and MOT defaults will be applied based on the number of cycles:

AC/HP ‐ MRT = 15, MOT = 5 (3 Cycles per hour)

Cycle rates can be increased or decreased in increments of 0.5 and will be inversely proportional to the MRT and MOT of reference of that system. For example, for a Standard Gas system if cycle rates is increased to 6, MRT = 5.83, MOT = 4.17.

If the user adjusts the setpoint to trigger a heaƟng or cooling call the MOT cycle would be canceled and the call would start immediately unless the system is an AC/HP in which case a minimum 5min MOT will be enforced. This 5min MOT for AC/HP will also be applied upon power up.

Heat/Cool Setpoints (Desired Temperature)

A minimum difference of 3° and maximum of 15° is enforced between heating and cooling desired temperatures.

Equipment On Indicators

When cooling equipment is on the Cooling icon will illuminate when the display is active. The perimeter lighting will glow blue if cooling is active. This could occur in cooling or auto mode depending on setpoint.

When heating equipment is on the Heating icon will illuminate when the display is active. The perimeter lighting will glow orange if heating is active. This could occur in the heating or auto mode depending on the setpoint.

When emergency heating equipment is on the Emergency Heating icon will illuminate when the display is active. The perimeter lighting will glow orange if heating is active. This could occur in the heating or auto mode depending on the setpoint.

When fan recirculation is active the fan recirculation icon will illuminate when the display is active. The perimeter lighting will glow green if fan recirculation mode is active, with operation mode is inactive.

When OpenADR is active the OpenADR icon will illuminate when the display is active. The perimeter lighting will glow yellow is OpenADR is active.

Please Note: If a call is pending but the system is not ready to run due to minimum off Ɵme, the corresponding mode icon will blink at a rate of 0.5s until it is ready to run at which point it will stay solid on.

Programmable Fan

The fan output can be programmed based on period of the day. When programming for each day and period the fan can be set to On, AUTO, or Circulation. If the fan button is pressed to change from On to Auto, Circulation, or vice versa when programmable fan has been enabled the manual change will only remain in effect until the next program period when the programmable fan setting will be changed per the scheduled setting. Fan circulation mode will turn on the fan for 33% of the time using 1h cycles, which includes the time that the fan is on due to an active heating or cooling call.

Schedule and Overrides

The schedule can be set up for each day of the week independently, with up to 5 different transitions per day using the mobile app. There is no backup schedule within the physical thermostat. Internet connection/service is required to establish back the schedule. Local time is not stored in thermostat and therefore the schedule will not be followed upon a POR and will require reconnection to the internet for proper timing. If internet connection is lost but there is no loss of power, thermostat will continue following the schedules even if there could be some drift in the time.

You can override schedule from the thermostat or mobile app. Schedule will resume after 4hrs if done through the thermostat unless a different time is set from the App. Overrides can be initiated both through the thermostat and App but duration can only be configured through the App with durations of 1‐23 hours, or the option of the override duration to be until the next schedule transition, or a permanent override.

TROUBLESHOOTING

If the display doesn’t power up after power is applied, check the Rc/Rh and C terminals for 24VAC. The display will not power up if polarity is reversed.

Reset

There are 2 different resets available for the thermostat:

Factory reset will restore all settings and operation to original out of the box settings. This includes Wi‐Fi, BLE, MATTER, and HVAC System type setup.
Network reset will restore default Wi‐Fi, BLE, and MATTER only. HVAC settings, including HVAC System type are not changed.

To perform a reset of the thermostat perform the following steps:

1. Press Fan + mode keys simultaneously for 10s. This will access the reset menu.

2. Use Arrow Up/Down to select the reset type
a. nr ‐ Network reset
b. Fr ‐ Factory reset.

3. If performing a Network Reset (nr) confirm the selection of network reset option with single press of fan button.

4. If performing a Factory Reset (Fr) confirm the selection of factory reset with two presses of fan button.

Please note performing a Network Reset or a Factory Reset will result in power on reset of the device.
