STATUS AND DIAGNOSTICS

he digital thermostat models are programmed to display a variety of status and diagnostic messages, depend-

ing on the operating conditions.

NOTE: The LCD temperature display may not agree with the temperature reading of your pool or spa ther-

mometer. The heater reads the water temperature at the inlet. Due to the circulation characteristics of any pool

r spa, the water temperature at the inlet to the heater may differ from that observed at a given location in the

pool or spa.

Display Condition

Heating

Call for heat established, flame

present

Spark Spark operating

No Demand Heat demand is satisfied

The following conditions are displayed in Pool, Spa

and Remote modes.

Display Condition

Sensor

Failure

Thermistor temperatures disagree

by more than 2°F

Sensor Open

Thermistor sensor failed open.

(Below -20°F)

Sensor Short

Thermistor sensor failed short.

(Above 217°F)

Flame w/o

CFH

Board is sensing flame when both

main and pilot valves are command-

ed shut.

PV Output

Fault

Pilot gas valve output is not in com-

manded state.

MV Output

Fault

Main gas valve output is not in com-

manded state.

LoNox Tab

Fault

Voltage is sensed at the Lo NOx ter-

minal on a non-Lo NOx heater (Lo

NOx tab is intact).

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/fireman switch circuit is

open.

Low Temp

Lockout

Water temperature below 36°F.

The following heat status messages are displayed in

Pool, Spa, and Remote modes when there are no

active fault conditions.

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/field 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 flow switch/field

switch #2 open.

Fan Lockout

3 fan switch faults within same heat

demand cycle, power must be

cycled to clear the fault.

Fan 5 Min

Delay

Heater shut down for 5 minutes

because LoNox fan switch didn't

close.

Ignition

Lockout

(Propane Tab

Broken)

Alternating with “No pilot

sensed” - Pilot flame not estab-

lished within the required time (15

sec or 90 sec).

Alternating with “Main Ign

Failure” - Pilot flame lost during the

8 second trial to ignite the main

burner.

Ignition

Failure

(Propane Tab

Not Broken)

Alternating with “No pilot

sensed” - Pilot flame not estab-

lished within 90 seconds.

Ign 6min

Delay

(Propane Tab

Not Broken)

Alternating with “Main Ign

Failure” - Pilot flame lost 4 times

within the 8 second trial to ignite the

main burner. Heater will lockout for

6 minutes before retrying.
