NOTE: Both the POOL and SPA setpoints will revert back to
65°F (18°C) and the POOL and SPA maximum temperature
settings will be 104°F (40°C). These setpoints will need to
be readjusted to desired settings.
NOTE: The LCD temperature display may not agree with
the temperature reading of your pool or spa thermometer.
The heater reads the water temperature at the inlet. Due
to the circulation characteristics of any pool or spa, the
water temperature at the inlet to the heater may dier
from that observed at a given location in the pool or spa.
5.4. Status and Diagnostics
The P-156 has a digital thermostat that is programmed
to display a variety of status and diagnostic messages,
depending on the operating conditions.
The following heat status messages are displayed in Pool,
Spa, and Remote modes when there are no active fault
conditions.
Display Condition
Heating Call for heat established, ame present.
Spark Spark operating.
No Demand Heat demand is satised.
Table K. Heat Status Messages - No Active Faults
The following conditions are displayed in Pool, Spa and
Remote modes.
Display Condition
Sensor Failure
Thermistor temperatures disagree by
more than 2°F (1°C)
Sensor Open
Thermistor sensor failed open. Below
-20°F (-29°C).
Sensor Short
Thermistor sensor failed short. Above
217°F (103°C).
Flame w/o CFH
Board is sensing ame when both
main and pilot valves are commanded
shut.
PV Output Fault
Pilot gas valve output is not in
commanded state.
MV Output Fault
Main gas valve output is not in
commanded state.
Internal Fault Board fault, replace board.
EEPROM Fault
Memory fault, reset set points,
replace board if fault does not clear.
Clock/Fireman Sw
Time clock/reman switch circuit is
open.
Low Temp
Lockout
Water temperature below 36°F (2°C).
Table L. Heat Status Messages - Active Faults
The following conditions are displayed only while there is
a demand for heat present.
Display Condition
Water Sw Open Water pressure switch open.
Vent/Field
Sw #1
Vent spill switch/eld switch #1 open.
Hi Limit 1 Fault High limit 1 open.
Hi Limit 2 Fault High limit 2 open.
Rollout Sw Open Rollout switch open.
Flow/Field SW #2
Field-supplied ow switch/eld switch
#2 open.
Ignition Lockout
(Propane Tab
Broken)
Alternating with “No pilot sensed” -
Pilot ame not established within the
required time (15 sec or 90 sec).
Alternating with “Main Ign Failure”
- Pilot ame lost during the 8 second
trial to ignite the main burner.
Ignition Failure
(Propane Tab Not
Broken)
Alternating with “No pilot sensed” -
Pilot ame not established within 90
seconds.
Ign 6min Delay
(Propane Tab Not
Broken)
Alternating with “Main Ign Failure”
- Pilot ame lost 4 times within the 8
second trial to ignite the main burner.
Heater will lockout for 6 minutes
before retrying.
