RH-HR
in.therm error (electronics)
An in.therm hardware error was detected (concerns the electronic circuit only).
▪
Trip then reset the main circuit breaker; make sure that the water heater restarts by changing the set point and by starting
and stopping each output (pumps).
▪
If the problem persists, replace the
in.therm
.
RH-NH
in.therm error (water heater)
This error occurs if the in.therm tries to heat the water but does not detect any increase in temperature.
▪
Check and see if the in.therm is connected properly (you should hear a click).
▪
Trip and then reset the main circuit breaker.
▪
Measure the voltage on the Di connector; you should read:
- 240vac at the Di connector: Pin 1 and Pin 2
- 120vac at the Di connector: Pin 5 and Pin 6
- 120vac at the Di connector: Pin 5 and Pin 2
▪
If the voltage is not correct, switch off then reset the breaker.
▪
If the voltage is correct, replace the
in.therm.
RH-NF
in.therm error ("no flow" condition)
This code appears when the in.therm detects a "no flow" condition (no flow).
▪
Make sure that the valves are open and that the water level is high enough.
▪
Check and clean the filters.
▪
Make sure that there are no air pockets (or that no object obstructs the passage of water into the in.therm channel). The
pumps can create strange sounds and error messages such as "P1 ER" that may appear on the display. Follow the air-lock
procedure to delete these messages.
▪
Make sure that pump coupled to the water heater (pump 1) turns by pressing the P1 button. If the message "P1 ER" appears
on the display, go to the pump 1 (error) section and follow the procedure.
RH-HL
The equipment overheating circuit has been tripped
There are 2 possible causes:
▪
The water heater has been stored in a place where it was very hot before installation and there is no water in the tube to
cool it: use a garden hose to cool the inside of the tube.
▪
The external ambient temperature is high enough to heat the water, even if the pumps are not operating.
- Add cold water into the spa and allow the heater to cool.
▪
Reset the
Spa Pack
with the circuit breaker.
RH-NC
Communication problem between
in.xm and the in.therm
▪
Make sure that the water heater cables are connected properly and that none of the wires on the cable connectors are
damaged.
▪
If the problem persists, the
in.xm
or the in.therm will need to be replaced (the two devices must be returned to find out
which of the two is defective).
