REPI Series Digital Thermostat Manual
REPI series thermostats are used to control room temperature in industrial, commercial and residential environment via controlling electric modulating valve with 0-10VDC (4-20mA) control signal or floating control as well as damper actuator of VAV system.
Electronic control technology is adopted, with green backlit LCD display of: working mode (cooling “
”, heating “
”, ventilating “
”, auto “
” ); fan speed (low “
”, med “
”, high “
”, auto “
”); room temperature; setting temperature etc. push button: On/Off “
”; mode changeover “
”; fan speed choose “
” and temperature adjustment “
” and “
”.
Shell: PC + ABS retardant material.

Operations:
"On/Off: Press “
” buttons to turn on; press “
” again to turn off.
"Setpoint: With thermostat on, press “
” to reduce the setpoint, press “
” to increase the setpoint, the setpoint step is 0.5 , the setpoint will be confirmed automatically after 5 seconds, and then return to dispay status, press “
” or “
” to check setpoint.
"Mode: With thermostat on, press “
” to change the working mode – Cooling “
” Heating “
”, Vent "
", Auto “
” ( Auto is available REPI-4/ REPI-4N).
"Fan Speed: With thermostat on, press “
” to select the desired speed – low speed “
”, Med speed “
”, High speed “
”, auto “
”. If single speed fan available, there’s only med speed “
”.
Under auto speed fan, the fan speed will be changed automatically as below: in low speed when room temperature is 1 difference with setpoint;in med speed when room temperature is 2 difference with setpoint; in High speed when room temperature is 3 difference with setpoint.
"Sleep: Thermostat will get into sleep function after programming.The set Temperature should to be.
