Interpreting Faults, Limits and Advisories
Your EASYHEAT communicates information about the way it’s operating. This section
explains these conditions and what you can do () to respond to them.
● ●
Fault
Heating interrupted; fault detected; correction required
to Control zone, ►Status then for fault notice
Low Coil Flow inadequate flow to coil
(FLS2, see schematic)
ensure water flow thru coil
ensure plug at power circuit
board
Low HSink Flow inadequate flow to unit
(FLS1, see schematic)
ensure water flow thru unit
ensure plug at control
circuit board
Coil shorted?…
…Increase caps
frequency out-of-range clean coil; remove bridging
call us (new caps)
●
●
HeatOn (Not regulating)
This occurs when the system cannot meet your Setpoint. It
lets you know that output is being restricted due to the
condition mentioned in the notice; Cutback Mode may be
displayed
Cap Over-Voltage
Cap Over-Current
capacitor exposed to too
much voltage...
reduce Setpoint
Contact Us
Heat Sink Hot heat sink near critical temp ensure adequate water flow
Enclosure Hot internal air near critical
temp
ensure adequate water flow
confirm internal fan op’n
Increase/decrease Taps to improve output/setpoint
match
See §3.5
See HeatOn (Limit) on
previous page
Cutback Mode
CAP TEMP PROTECT
+ REDUCE OUTPUT
peak current protection;
you note output falls with
increased setpoint
reduce setpoint
part out of coil, thru Curie?
follow ‘adjust taps’ notices
You may be able to correct frequency (Adjust Caps message) by adjusting coil with more
(lowers frequency) or fewer (increases frequency) turns; if your coil design is fixed, call
us for replacement caps
●
Advisory *
See asterisk on display. Indicates output/setpoint are not well
matched; more efficient configuration may be possible.
