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. SEE FIG. 8.
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.
0 ohms (SHORT CIRCUIT), REPLACE SETPOINT PANEL.
RECONNECT ALL LEADS AND CHECK OUT SYSTEM.
TEMPERATURE ABOVE 106°F.
DISCONNECT SENSOR LEADS FROM CONTROL.
MEASURE SENSOR RESISTANCE WITH OHMMETER.
CHECK VOLTAGE: T8205/Q8205 24V TERMINALS;
TS8205/Q8205 + AND - TERMINALS.
RESISTANCE ABOVE 15K ohms (OPEN CIRCUIT).
FIX LOOSE OR BROKEN WIRES. REPLACE SENSOR, IF NECESSARY.
MEASURED AND ESTIMATED RESISTANCE
DO NOT MATCH.
REPLACE SENSOR. RECONNECT ALL LEADS AND CHECK
OUT SYSTEM.
TEMPERATURE 105°F (40°C) TO 106°F (41°C).
CONTROL OK. CHECK BALANCE OF SYSTEM.
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.
ABOVE 15K ohms, FIX LOOSE OR BROKEN WIRES;
REPLACE IF NECESSARY.
FOR T8205B,C/TS8205B,C MODELS REPLACE THE CONTROL SYSTEM.
FOR T8205A,H/TS8205A MODELS, REPLACE THE T8205A,H/TS8205A OR
