Changes compared to older style fuse board:
G
Fuse: (FC3) has been removed, since the
F1 fuse was added to the ICB
H Fuse: (FC4) is now a 3A fuse, matching
the FC1 & FC2
NOTE: Fuses located on THIS board are all 250v SLO-BLO 5 x 20 mm.

The control continually compares the set temp to the actual water temp. When
the water temp is 1º below the set point the following sequence starts:
1. The control checks for open blower vacuum switch
2. Blower starts pre-purge cycle as the ignitor heats up (20 Sec).
3. The control checks for a closed blower vacuum switch.
4. At proper ignitor temp, a 4 second trial begins. Gas valve opens and
monitors flame sense. The blower will turn off for one second. The ignitor
is de-energized at flame sense or at completion of 4 sec trial. If the flame is
sensed, The blower vacuum switch, control loop, temp sensor & flame
sensor are constantly monitored during call for heat.
5. When set temp is reached, the control ends the call for heat. The gas valve
is de-energized, and the flame is extinguished.
6. The blower will operate for a 30 second post purge.

UHS Sequence of Operation: Normal
NOTE: If during step four, the heater fails to fire, please procced to the next page for
more details outlining failure to light operations.
If trial fails:
1. Gas valve de-energizes (for 30 second, blower post purge).
2. Starts over at #2 of heating mode sequence.
3. Retries 3 times until lockout (IF code).
4. Waits 60 minutes then retries 3 more times.
5. Will continue to retry every 60 minutes, until demand for heat is
stopped.
NOTE: When making keypad entries of any type there may be a 5-10 sec delay for
certain situations.
