FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL AND SYSTEM COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
PRODUCT OVERVIEW
The R02P034 is our most powerful thermostat yet. Control your home comfort system powered by an improved full LED display control unit with touch sensitivity. Adjust the desired temperature with a wide setpoint range of 41°F to 95°F.
The unit works well with 24 VAC ClimateTalkTM architecture; powered by gas, electric heat, heat pumps, and central air conditioning based systems. With smart systems such as autoconfigure, a utochangeover and advance diagnostics, you can take a hands off aproach, while letting it do the heavy lifting for you. Additional features include humidity control, dehumidification control, dual fuel control, and filter change-out indicator. The R02P034 is the full package in home control systems.
WARNING Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC/CEC code.
WARNING To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.

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.
- Using a flat a screwdriver, carefully separate the the top of the thermostat body from the base.
- Swing the base open and detach it from the body.
- Connect wires to terminal block on base.
- Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
- Attach base snugly to wall using the two provided mounting screws. Levelling is for appearance only and will not affect thermostat operation.
- 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.
Clock Setting
To set the time and day, press the button. 
Clock will be displayed. Use the
and 
buttons to adjust the blinking value. Press to switch between setting the hours, minutes and day.
Once completed, press to return to the main display
Schedule Setting
By default, the scheduling mode is disable. Refer to section 3 to set the desired schedule type.
When scheduling is enabled, press to enter clock configuration (see section 2.3). Using the button to skip over the clock parameters, the schedule paramaters will be displayed
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:
- Period start time (hours)
- Period start time (minutes)
- Operating mode during the period
- Fan mode
- Modulation (unused)
- 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.
Alarms
The thermostat will display 
when an alarm is raised. The alarm code will be shown in the top-left corner.
