Problem
Check / Verify
Possible Cause
Low Temperature Within Room
Misplacement of thermostat
location within room.
Make sure thermostat is not being
influenced by an additional heat source,
such as lighting or air duct.
Low temperature setting of the
thermostat.
Adjust the temperature setting on
thermostat.
The system fails to turn on if the
thermostat is set to high setting
Thermostat may be out of calibration or
defective. Replace thermostat.
The electronic actuator fails to open
during a call for heat
The electronic actuator may be improperly
seated or may be defective. Replace if
necessary.
Wiring from heat source to panel.
Check that the wiring is done properly.
Consult qualified electrician prior to
alteration of wiring between heat source
and panel.
Output of heat source is unable to
meet demand of heating system.
Compare output of heat source to the
requirements of the heating system.
Pump is not on during a call for
heat. (Use a stethoscope or similar
device to verify)
The wiring or pump may be defective.
When zone valves are installed
outside the panel a qualified
electrician should verify 24V power
is supplied to the thermostats and
actuator.
The 24V transformer may have failed. Any
zone valves must be opened manually to
avoid dead-heading of the pump.
High Temperature Within Room
Check current setting of the
thermostat.
Adjust the temperature setting on
thermostat to a lower setting.
Installed electronic actuators
remain open after the thermostat is
satisfied.
An obstruction inside the zone valve is not
allowing the actuator to fully close or the
thermostat is still calling for heat.
