Solution
Flow is too high at
current setpoint.
Use a smaller mix chamber
that is rated for the unit
in use. If recirculating,
decrease flow or decrease
temperature setpoint.
Bad RTD or bad
RTD placement
against heater.
Swap A and B heater output
cables and RTD cables and
see if issue follows. If so,
replace RTD.

should be 9-12 Ω for 10
kW systems and 6-8 Ω
for 15 kW systems. If out
of tolerance, check for
loose heater rod wire(s).
Reconnect wires or replace
heater rod if necessary.
