ELECTRICAL (SOLID STATE THERMOSTAT IID)

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

Check voltage at 24 V terminals.

VOLTAGE BETWEEN 21.5-28.5 V.

Set control to max. temperature. After 2-3 cycles, check water temperature.

VOLTAGE OUTSIDE RANGE 21.5-28.5 V. Check transformer, 120 V supply, correct as necessary

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

TEMPERATURE 105-106° F. Control ok.

RESISTANCE 1-14k OHMS.

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

RESISTANCE O OHMS (SHORT CIRCUIT) 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 but less than

15 k ohms, replace potentiometer.

Above 15k ohms, fix loose or broken wires; replace potentiometer if necessary.

Reconnect all leads and check out system.

MEASURED AND ESTIMATED RESISTANCE DON'T MATCH.

Replace sensor. Reconnect all leads and check out system.
