Proheat T-I - Manual (Page 13)

Diagnostics
When the Timer is installed on a PROHEAT
heater, the Timer's red 'Heater activated
light' will be lit constantly while the heater
is running normally. In the case of a heater
error, the Timer's red light will flash an
error code followed by a pause.
Example: Repeatedly flashing five pulses separated
by a pause indicates a heater voltage error.
The PROHEAT heater error codes
are as follows:
1 Flash .............Star t error
2 Flashes..........Flame out
3 Flashes..........Coolant flow
4 Flashes..........Overheat
5 Flashes..........Voltage
6 Flashes..........Flame sensor
7 Flashes..........Temp sensor
8 Flashes..........Fuel pump
9 Flashes..........Compressor
10 Flashes..........Ignition coil
11 Flashes..........Coolant pump
12 Flashes..........Blower
13 Flashes..........Sleeper fan
These errors correspond to those
displayed on the PROHEAT Control
Module diagnostic panel.
