10) Low battery warning
The controller has a two-stage lower battery warning system. When the batteries are first
detected to be weak, the first stage low battery warning is indicated by
BATT
flashing on the
LCD display. At earliest convenience, the batteries with 2 new AA alkaline batteries should be
replaced.
When the batteries become too weak for normal operation, the controller enters the second
stage low battery warning which shuts down the controller. In this condition,
BATT
flashes alone
on the display screen and the thermostat will turn unit off. The unit will remain shut-off until the
batteries are replaced.
The controller will still keep the current set temperature and filter run-time in memory until new
batteries are installed. After confirming that new batteries have been inserted, the controller will
return to normal operation.
2.5 Installation of wired controller
Caution:
This controller cannot connect with 110/220 and 380V power.
To prevent electrical shock and / or unit damage, disconnect electric power to unit at main
fuse or circuit breaker box until installation is complete.
Electric / gas switch:
This controller is configured from the factory to operate a heat/ cool, fossil fuel (gas, oil, etc.),
forced-air system. It is configured correctly for any system that DOES NOT requires the
controller to energize the fan on a call for heat.
If the system is an electric heat or heat-pump system that requires the controller to turn on the
fan on a call for heat, locate the
ELEC
/
GAS
switch on the back of the controller and switch it to
the
ELEC
position.
This will allow the controller to energize the fan immediately on a call for heat. If it is unsure if the
heating/ cooling system requires the thermostat to control the fan, contact a qualified heating
and air conditioning service person. When the controller is configured for heat pump, the
controller will always power the circulator fan on a call for heat in the heat mode. The
ELEC
/
GAS
switch must be set to match the type of auxiliary heat system uses for proper
operation in the emergency mode.
