PS4000/PS5000 Touchscreen Programmable Thermostat
Battery Tips
1.
Replace the batteries as soon as “Batt”
flashes in the display. The Battery indicator
flashes in the display one month before the
batteries run down completely.
2.
Always use fresh AA alkaline batteries.
Non-alkaline batteries do not last as long
and can leak, causing thermostat damage.
3.
Although the thermostat has a Low
Battery indicator, replace the batteries once
a year to prevent the thermostat and
heating/cooling system from shutting down
due to lack of battery power.
