A.
Installation, Mounting
Caution: Turn off 0769008 and the electrical devices (e.g. heater, cooler) which will be
connected before installation.
It is highly recommended that the installation procedure is processed by trained
personnel.
1.
Installation Location
The thermostat should be mounted on an inner wall 1.5m above the floor in position
where it is readily affected by changes of the general room temperature with freely
circulating air. Prevent direct exposure to sunlight; dripping or splashing area. Do not
place this unit at a location where air circulation is low, or where it has great temperature
changes (e.g. near door). Do not place the thermostat near heat/cool generating sources.
2.
Wiring
There are 3 wiring terminals at the bottom of 0769008 base housing, labeled as
"C"(COOL), "H"(HEAT) and "L”(LIVE). Connect Cooler and Heater to the "COOL”
and "HEAT" terminals. Leave unused holes blank.
Wire the correct cables to the terminal block according to the circuit diagram at the back
of the thermostat. Push all cables back into wall prior to fixing to avoid trapping wires. It
is recommended that a 6A fuse is fitted.
