Inserting batteries
Using a small screwdriver or similar probe, push down
through the hole in the top of the thermostat until some
resistance is felt, then pull forward to split the front of the
thermostat from the backplate.
Insert 2 X AA batteries into the thermostat, observing
correct polarity. When the power is applied for the first
time, the display must show,Time, Day, Room
temperature, P1 and a Sun symbol. If not, press reset
button until the above display appears.
Heater/Cooler selection
Mounted on the left hand side and above centre of the
thermostat PCB are three DIP switches, these are used
to control the differential and the heat/cool system.
The switches must be set before the batteries are
installed. For Heating, switch number 3 must be in the
ON position. For Cooling, switch number 3 must be in the
OFF position. To change from heater to cooler and vice
versa, the batteries must be removed, and the display
cancelled, the reset button must be pressed when the
batteries are re-installed.
Differential setting
Differential is the difference between the unit
switching OFF and switching back ON again. For
example, with a 1ºC differential, if the ‘stat Switches OFF
at 20ºC, it will drop back 1ºC and then switch back ON
again.
RF Address code setting (See Fig. 1 )
Switch off power to the receiver and remove batteries
from thermostat.
To set the address code, remove at least two of the
‘jumpers’ on the thermostat pcb. (park the ‘jumpers’ on
one of the jumper legs). Where a ‘jumper’ is removed, the
corresponding DIP switch on the receiver must be moved
to the OFF position. Replace batteries into the receiver
and press the reset button. Switch on the power to the
receiver. Set the thermostat to demand heat. The rotating
icon will appear on the display to indicate heating
demand and the green light will illuminate on the
receiver. On initial set up, it may take up to two minutes
for this to appear. In a cooling application, it may take up
to four minutes for the icon to appear initially.
