HL8102 Series Digital Thermostat Manual
HL8102 series thermostats are used to control room temperature in industrial, commercial
and residential environment via cont rolling 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.
Function :
Detect and Display room temperature
Room temperature setting
Fahrenheit or Celsius degree display
Timing sleep
Control On/Off of cooling and heating equipment
Selectable single speed or three spe ed fan control

Operations:
On/Off: Press “ ” buttons to turn on; press “ ” again to turn off.
Setpoint: With thermost at on, press “ ” to reduce the setpoint, press “ ” to increase t he set point , the se tpoint st ep 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 workin g mode – Cooling “ ”， Heating “ ”, Vent " ", Auto “ ”
( Auto is available from HL8102E to HL8102K).
Fan Speed: With thermostat on, press “
” to select the desired speed – l ow speed “ ”, M ed speed “ ”, High speed
“ ”, auto “ ”. If single speed fan available, there’s only med speed “ ”.
Under auto speed fan, the fan speed will be changed aut omat icall y as be lo w: in low spe ed when room t emperatur e
is 1℃ difference with setpoint;in med speed when r oom te mperatur e is 2℃ difference with setpoint; in High speed when
room temperature is 3℃ difference with setpoint.
Sleep: Thermostat will get into sle ep function after programming.T he 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 ho urs; thermostat will r eturn to the working stat us 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.
