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

Operations:
" On/Off: Press “ ” buttons to turn on; press “ ” again to turn off.
" Setpoint: With thermostat on, press “
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 “
( Auto is available REPI-4/ REPI-4N).
" Fan Speed: With thermostat on, press “
“
”, 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.
” to reduce the setpoint, press “ ” to increase the setpoint, the setpoint step is
” to change the working mode – Cooling “ ”， Heating “ ”, Vent " ", Auto “ ”
” to select the desired speed – low speed “ ”, Med speed “ ”, High speed

To set：Press “ ” button for 3 seconds till “ ” display, there’s a number of count down in the center of LCD, Use “ ” or
“ ” to adjust the desired sleep time: the max. = 48 hours; thermostat will return to the working status after 5
seconds, “ ” is flashing to start counting down. The setpoint should be replaced by the sleep setpoint.
To quit: When thermostat get into Sleep function, “
" Keypad lock: press “ ” and “ ” for 10 seconds till to “ ” display to activate, under this function, any keypad is locked.
Press “ ” and “ ” for 10 seconds till “ ” disappear to quit the function.
" Set Parameters: With thermostat off, press “
” will flash, press “ ” or “ ” to quit.
” for 10 seconds to enter menu to set the parameters.
