1. Introduction
Keys
This wireless thermostat has 8 input keys: COMF/ECON, , , PROG, OK, __, SET, and
internal RESET Button.
Keys Functions
COMF/ECON Select Comfort, Economy or Defrost set-temp
and Adjust the desired set-temperature
PROG Cancel program override/ select program in program setting mode
OK Return to normal mode
__ Button Turn on setback function in heating system/ switch to off mode in
cooling system
SET Enter setting modes/ change program day in program setting mode
RESET Reset the thermostat to default state. This key is located on the PCB
Reset
This wireless thermostat will be hard reset after reset button is pressed. It will be soft reset after
power up.

2. Technical Characteristics
2.1. Heating system
2.1.1. Pulse Width Modulation (PWM)
This wireless thermostat offers Pulse width modulation control that enables a set point
temperature to be maintained in a precise and convenient way. In the case of under floor heating,
the duration of opening for the valve actuator is regulated by comparing continuously the set point
temperature with the actual temperature. In this way, the room temperature can reach the set
temperature with minimal temperature deviation. Subsequently, the room temperature is
constantly maintained via the PWM control. In the case of the thermostat is used with radiator or
convector heating system, PWM can be switched off if necessary.
2.1.2. Setback Temperature
This wireless thermostat has setback temperature function. Once the setback button is activated,
the set point temperature is 30C or 60F lower than the Econ set-temp. For example, if the Econ
set-temp is at 220C, then the setback temperature is 190C.
Press __ button to toggle between normal set-temperature and setback function, icon will
flash and animate to indicate that the setback function is activated.

2.1.3. Frost Protection
The thermostat can be made to offer frost protection. After enable this function, the set-point
temperature become 50C(410F).
To activate the frost protection, press and hold COMF/ECON buttons for 1.5 seconds. Frost
protection indicator is animating to indicate that the frost protection function is activated.
2.2 Cooling function
This wireless thermostat offers the selection of using the devise in cooling system. In this case,
turning the “Heat/Cool” switch to on position to activate the Cooling. In the case of cooling,
PWM is switched off automatically.
Press __ button to toggle between off mode and normal operation. Cool mode indicator is
animating to indicate off mode is set.
