LCD Electronic Thermostat
Code: 0769004,
Reference: KT4-LCD-NP
Before Installation
Turn off 0769004, all electronic source and electrical devices
which will be connected before installation and maintenance.
The installer must be a trained service personnel.
Installation Location
The thermostat should be mounted on an inner wall ~1.5m above the floor in a position
where it is readily affected by changes of the general room temperature with freely
circulating air.
Prevent direct exposure to sunlight, drip or splash.
Do not place the unit at a location where air circulation is low, or where there are great
temperature changes (e.g. near door). Do not place the thermostat near heat generating
sources (e.g. radiators, hot air vents, TV or lights).
Wiring the Terminal
For 0769004, there are 3 wiring terminals at the back of the thermostat which are labeled
as “NC”, “NO” and “L”. Connect L to Live and NO to Heater or Cooler. Where NC is a
Normally Close Valve.
Mounting
1.
Ensure that the surface is level.
2.
Place the cables at the hole near the terminal block.
3.
Insert 2 pcs of wall anchors into the holes of the wall.
4.

shown in the below figures.
Opening
Pull out the battery drawer and then lightly press on the spots shown below in order to detach

Start / Reset
When the system is reset, all the LCD segments are ON and the measured temperature will be
displayed after a while. Low Battery Check will be done at startup. when battery is low,
will be displayed and please replace the battery.
*If there are any display or functional errors, please remove the batteries for about 30
sec to reset the thermostat.

Use 1.5V/cell alkaline batteries 2 pieces.
Maintenance
Caution: Switch off all electric sources before maintenance. We recommend
that the maintenance should be performed by a
trained personnel.
No heating / cooling control:
Check the thermistor sensor performance by measuring the corresponding
variable resistance under different temperatures, if it is in good condition, the
LCD value will change accordingly, if not, trace the control circuit or the
LCD connection, replace the thermistor sensor if necessary. If there is a
problem with the control circuit, replace the PCB if necessary.
