PROBLEMS AND SOLUTIONS
PROBLEM
The thermostat goes to « OFF » after seconds into operation
or
The thermostat heating indicator is on but system doesn’t work.
The heating system always on.
The thermostat loses programming and time.
Programs do not change as you want.
Erratic display.
Convector fan does not work well.
Battery test / Batt lo.
The thermostat moves to « OFF » and locks in.
The lights are flickering.
Room temperature shown is wrong.
The thermostat temperature is hot.
CAUSE
-Installation not compatible with the specifications.
-Load is less than 500 W.
-Operating voltage is not 120/240 VAC.
-Bad installation.
-Defective batteries or bad contact in battery compartments.
-Wrong programming.
-Wrong mode selected.
-Wrong mode selection of heating system.
-Defective batteries.
-Battery have a bad contact.
-Polarity is wrong.
-Circuit breaker is open.
-Power failure.
-A draft is near thermostat.
-The electronic thermostat uses a solid state component to control the power delivered to the load. Bigger is the load, higher is the temperature dissipated by the thermostat.
-The housing temperature can reach 45°C under 3500 W load.
SOLUTION
-If the thermostat is driving only a high voltage contactor, add a 500 W load on the circuit.
-Check if wires are not shorted between the thermostat and the electric box.
-Press reset button.
-Check batteries and the polarity.
-Straighten contacts placed inside battery compartment door.
Check actual time in AM & PM as well as program times (AM is not displayed).
-Make sure operation mode is at « AUTO ».
-Press reset button.
-Make sure switch #1 is in « ON » position.
-Press reset button.
-Change batteries.
-Straighten contacts placed inside batteries compartment door.
-Place batteries in right polarity.
-Check line voltage presence at the thermostat.
-Use the ON/OFF control mode (see instruction manual).
-Eliminate draft.
NOTE : THE THERMOSTAT CANNOT BE PROGRAMMED IF IT IS NOT CONNECTED ON THE 120/240 VAC LINE.
