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.
Low supply mixed fluid temperature.
Voltage supplied to Electric Boiler may be less
than 240 volts, causing the boiler to read the water
temperature as slightly higher than it actually is.
Increase the setting on your boiler to compensate.
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.
The user setting may be too low.
Turn up the user setting on the electric boiler.
Circulator is not on during a call for heat. (Use
a stethoscope or similar device to verify)
Check that the wiring is done properly. Consult
qualified electrician prior to alteration of wiring
between pump and electrical box.
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. If this so, switch
the power module to Bypass mode. This will provide
constant circulation so long as there is still 110V
power to the panel. Prior to Bypass mode selection,
any zone valves must be opened manually to avoid
dead-heading of the circulator.
High Temperature within Room
Check current setting of the thermostat.
Adjust the temperature setting on thermostat to a
lower setting.
High supply mixed fluid temperature.
Adjust the Thermostatic Mixing Valve to the
appropriate settings.
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.
Low Water Temperature
Check current setting of the aquastat.
Adjust the temperature setting on aquastat to a higher
setting.
Circulator is not on during a call for heat. (Use
a stethoscope or similar device to verify)
The power box or circulator may be defective.
The red and green LED’s on the power module
do not light up during a call for heat.
The power box may be defective.
High Water Temperature
Check current setting of the aquastat.
Adjust the temperature setting on aquastat to a lower
setting.
