The unit requires 2 x AA 1.5V Batteries.
Batteries should operate for approximately 18
months.
Only good quality 1.5V alkaline batteries
should be used. DO NOT use re-chargeable
batteries as they only have a terminal
voltage of 1.2V nominal.
To replace batteries remove the Room Stat
from its back plate. Gain access by using a
flat headed screwdriver inserted into the slot
underneath the unit.
Note that if the batteries are removed for more
than 30 seconds, the set temperature will be
lost.
If the batteries are not replaced and no signal
is received by the receiver the red room stat
signal light will be illuminated on the boiler
mounted RF Timer.
After 1 hour the boiler will operate in
“Emergency Mode” with a continuous, but
reduced temperature until the batteries are
replaced.
