What to do:

A. Try resetting the controller by turning its AC power OFF and

then ON.

B. If “No Heat” persists, then the problem could be one of the

following.

a- Open heater or load.

b- Thermocouple shorted. Switch to manual mode to

override this condition.

c- Load circuit open. This can be caused by an open power

cable, an open connector or a failed triac in the

controller. Exchange the module with a known good

module to eliminate suspect triac or module.

d- Slow heater. Use higher power heater or operate in

manual mode until setpoint is achieved.

e- Thermocouple too far away from heat source which

causes less than 2 degrees F (1°C) rise in 60 seconds due

to thermal lag. Move thermocouple as close to heater as

possible or use heater with built in thermocouple.

f- To defeat “No Heat” circuit, if not used or required,

remove jumper J4 and that circuit will no longer be

active.

User’s Selected Jumper Option

1- For degree Celsius operation,

install jumper on PC board marked J1

2- For 50 Hz operation

install jumper on PC board marked J2

Since the microprocessor reads the status of the jumpers during

power up, the power has to be turned off and on again in order to

activate the jumper function.
