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 °C, 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 °C difference with setpoint;in med speed
when room temperature is 2 °C difference with
setpoint; in High speed when
room temperature is 3 °C difference with
setpoint.
 Sleep: Thermostat will get into sleep function
after programming.The set Temperature should
to be.
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, “ ” will flash, press “ ” or “ ” to quit.
 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
“ ” for 10 seconds to enter menu to set the
parameters.
