Temperature Control Span :
It controls how much the room
temperature can be deviated from the setpoint. A smaller degree
will result in a more accurate control. A larger degree will result in
less on/off cycling and it usually saves more energy.
Fan Control :
It should be set according to the type of Heating
system used. Select “E” for Electric Heat, fan will be On when Heat
is On. Select “O” for Gas Heating or Oil Heating, fan will NOT be on
when Heat is On.
Heater Minimum Off Delay :
It should be set according to the
heater type. Select “L” if compressor is used for heating. Select “S”
when a compressor is not used.
Temperature Calibration
This thermostat is calibrated at factory and calibration is generally
not required. However, in the event that a deviation is found.
1. In Normal Display Mode, press and hold UP and DOWN buttons for 5
seconds to change the temperature calibration display and the current
temperature will flash,
