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. Adjust the Mixing Valve to the appropriate
settings.
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.
Circulator is not on during a call for heat. (Use a
stethoscope or similar device to verify)
The StatLink®module or circulator may be
defective.
A qualified electrician should verify 24V power is
supplied to the thermostats and actuator.
The 24V transformer may have failed.
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 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.
Maintenance
Yearly maintenance should be done on the panel prior to each heating season to ensure the ecient and accurate
operation of the panel.
Complete the following check list:
• Raise all thermostats to cause a call for heat within the system. Verify that the circulator starts, via a stethoscope or
similar device.
• Conrm that the Auxiliary Contacts close.
• If applicable, verify that each zone valve opens during the call for heat – the actuator should be warm to the touch, the
LED will light up (on 5620x models) and the white indicator should rise from the top of the actuator.
• Return all thermostats to a desirable setting.
You are now ready for another heating season with HeatLink.
