Installation

This booklet contains installation instruction and information on the thermostat only. Separate installation instructions for the furnace or air handler and outdoor AC condensing unit or heat pump are provided.

Wiring Requirements

Each communicating device in the system has a four wire connection labelled (R, C, 1, 2). Each R, C, 1, and 2 terminals must be wired consistently. Maximum length from the thermostat to the indoor unit is 100 feet.

Installing Thermostat

The thermostat should be placed where the temperature is representative of the general room
conditions, away from cold or warm air draughts, radiant heat and direct sunlight. The thermostat must not be installed on an outside wall.

1. Using a flat a screwdriver, carefully separate the the top of the thermostat body from the base.
   

2. Swing the base open and detach it from the body.
   

3. Connect wires to terminal block on base.
   

4. Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.

5. Attach base snugly to wall using the two provided mounting screws. Levelling is for appearance only and will not affect thermostat operation.
   

6. Carefully line up the bottom of the thermostat with the base and snap into place.

This button also allows to exit any settings menu.

Fan Modes
Press to switch between Fan On and Fan Auto. When the thermostat displays AUTO FAN, the circulating fan will run only when there is a heating or cooling demand. Otherwise, the fan will run continuously.

Operating Modes
The operating mode can be changed using the key.
Heat : Heating with the primary heating source (heat pump if present, or furnace).
Auxiliary Heat ( and ): Heating with the auxiliary heating source (furnace). This is only available when a heat pump is connected.
Cool ( ): Cooling mode is only available when a heat pump or A/C unit is connected.
Auto (and ): The thermostat will automatically switch between heating and cooling modes. When there is a demand for the selected mode, the matching icon will start blinking and the thermostat will command the system to operate.

Start is displayed indicating the start time of the current period is being set. Use and to adjust the blinking parameter, and use to advance to the next one, in this order:

1. Period start time (hours)
2. Period start time (minutes)
3. Operating mode during the period
4. Fan mode
5. Modulation (unused)
6. Set point

The blinking cursor will cycle through these parameters for all periods, and for all day groups. Once the schedule is set, to enter this mode press and hold at the main display.
