VOLTAGE: T8205/Q8205 BETWEEN 21.5 TO 28.5V;
TS8205/Q8205 BETWEEN +0.2V AND 0.75V.
SET CONTROL TO MAXIMUM TEMPERATURE. AFTER
TWO TO THREE HEATING CYCLES, CHECK WATER
TEMPERATURE.
RESISTANCE 1 TO 15K ohms.
CHECK WATER TEMPERATURE; ESTIMATE EXPECTED
SENSOR RESISTANCE FROM SENSOR RESISTANCE TABLE.
MEASURED AND ESTIMATED RESISTANCE
MATCH WITHIN 20 PERCENT.
DISCONNECT POTENTIOMETER LEADS FROM CONTROL.
MEASURE RESISTANCE WITH OHMMETER.
IF RESISTANCE IS:
0 TO 100 ohms AT MINIMUM SETTING;
9 TO 11K ohms AT MAXIMUM SETTING,
REPLACE CONTROL MODULE.
ABOVE 11K ohms, REPLACE SETPOINT PANEL.
ABOVE 15K ohms, FIX LOOSE OR BROKEN WIRES;
REPLACE IF NECESSARY.
RECONNECT ALL LEADS AND CHECK OUT SYSTEM.
TEMPERATURE BELOW 105°F (40°C).
DISCONNECT SENSOR LEADS FROM CONTROL.
MEASURE SENSOR RESISTANCE WITH OHMMETER.
CHECK VOLTAGE: T8205/Q8205 24V TERMINALS;
TS8205/Q8205 + AND - TERMINALS.
VOLTAGE OUTSIDE RANGE: T8205/Q8205 21.5 TO 28.5V;
CHECK TRANSFORMER AND 120V SUPPLY; CORRECT
AS NECESSARY. TS8205/Q8205 +0.2V TO 0.75V,
CHECK GENERATOR; CORRECT AS NECESSARY.
RESISTANCE 0 ohms (SHORT CIRCUIT).
CHECK SYSTEM FOR SHORTED WIRES. REPLACE
SENSOR, IF NECESSARY.
MEASURED AND ESTIMATED
RESISTANCES DO NOT MATCH.
REPLACE SENSOR. RECONNECT ALL LEADS AND CHECK
OUT SYSTEM.
TEMPERATURE 105° (40°C) TO 106°F (41°C).
