ELECTRICAL (SOLID STATE THERMOSTAT MILLIVOLT)

If the pool/spa/hot tub water is too cold, troubleshoot the system as follows:

Check voltage at + and - terminals.

 

 

 

 

 

 

 

 

VOLTAGE BETWEEN + 0.2 V and 0.75 V.

 

VOLTAGE OUTSIDE RANGE + 0.2 V and 0.75 V.

(Polarity is critical)

 

Check pilot generator, correct as necessary.

Set control to max. temperature. After 2-3

 

 

 

 

 

 

 

 

 

 

cycles, check water temperature.

 

 

 

 

 

 

 

 

 

 

 

 

 

TEMPERATURE BELOW 105°F Disconnect sensor leads from circuit board. Measure sensor resistance with ohmmeter.

TEMPERATURE 105-108° F. Control ok.

NOTE: 108°F is the upper control limit.

RESISTANCE 1-14k OHMS.

Check water temperature; estimate expected sensor resistance from chart below.

RESISTANCE O OHMS (SHORT CIRCUIT) OR OPEN CIRCUIT GREATER THAN 14 K.

Check system for shorted wires or open circuits. Replace sensor if necessary.

MEASURED AND ESTIMATED RESISTANCE MATCH WITHIN 20 PERCENT.

Disconnect potentiometer leads from circuit board. Measure resistance with ohmmeter. If resistance is:

0-100 ohms at minimum setting:

9k to 11k at maximum setting,

replace circuit board. Above 11k ohms, replace

potentiometer.

0 ohms (short circuit), replace potentiometer.

Reconnect all leads and check out system.

MEASURED AND ESTIMATED RESISTANCE DON'T MATCH.

Replace sensor. Reconnect all leads and check out system.
