Troubleshooting
Issue Cause Solution
No heat 1. No call for heat from the
thermostat
2. Loop valves are not open
3. No power to the heat source
or broken heat source
4. No power to the pump or
broken pump
5. If using zoning options, valves
are not opening
6. Isolation valve is not open
7. Air locked (air in the system)
1. Make sure the thermostat is connected correctly. Make sure setpoint is
at the desired level
2. Make sure all valves are open and, if necessary, balanced.
3. Make sure the breaker for the unit hasn’t tripped. If not, make sure
the unit is wired correctly. Make sure there is a call for heat (from
the thermostat). If this does not solve the problem, contact Uponor
Technical Services.

4. Make sure the breaker for the unit has not tripped. Check the fuse
inside the boiler. If not, make sure the unit is wired correctly. Make sure
there is a call for heat (from the thermostat). If this does not solve the
problem the pump needs to be replaced.
5. Make sure the controls have power. Make sure the controls are wired
correctly. Make sure there is a call for heat and actuators are opening
up. Remove actuator and make sure water is flowing through the loop.
If water is flowing through, replace actuator.
6. Open valve.
7. If pump is operational and all loops are open and there is no flow
(check flow meters) then the system most likely is air locked
(meaning air is trapped in the system preventing flow). Fill and purge
the system. See Section 6: Filling and Purging.
Low heat 1. Thermostat setting
2. Boiler set point is too low
3. Pump setting is wrong
1. Make sure the thermostat setpoint is at the desired level.
2. Make sure the setpoint on the boiler matches the design criteria
(driven by installation method, flooring and heat demand).
3. Make sure the pump setting (1-3) is set at the correct position for
the design.

1. Breaker tripped
2. Wired incorrectly
3. Faulty control
1. Make sure the breaker hasn’t tripped. If so, reset.
2. Check wiring.
3. Contact Uponor Technical Services.
