Description
Checks
Solutions
"Ignit Error"
1
Three unsuccessful ignition attempts in
a row
a- Check gas supply
pressure;
b- Check ignition spark
c- Correct amount of gas;
d-Check for120VAC at the
gas valve;
a- If the gas supply pressure is
incorrect, it must be adjusted to the
correct pressure;
b- If spark is not present check for
correct ignition electrode position;
c- If the combustion air pressure is
incorrect, inspect the vent system
and eliminate any obstructions;
d- If the voltage to the gas valve is
not 120Vac the power control board
must be replaced.
"Gv Relay Error"
2
Failure detected in the GV (gas valve)
Relay
a- Check the integrity of the
wire connections between
gas valve and control board.
a- If wires are damaged, replace
them
b- If wires are ok, replace the gas
valve or the power control board.
"Gv Relay Not Open"
3
Failure detected in the GV (gas valve)
Relay
a- Check the integrity of the
wire connections between
gas valve and control board.
a- If wires are damaged, replace
them;
b- If wires are ok, replace the gas
valve or the power control board.
"Gv Relay Not Close"
4
Failure detected in the GV (gas valve)
Relay
a- Check the integrity of the
wire connections between
gas valve and control board.
a- If wires are damaged, replace
them;
b- If wires are ok, replace the gas
valve or the power control board.
"Safety Relay Error"
5
Failure detected in the Safety Relay
Replace the power control board
"Safety Relay Open"
6
Failure detected in the Safety Relay
Replace the power control board
"Safety Relay Closed"
7
Failure detected in the Safety Relay
Replace the power control board
"Blocking Too Long Error"
11
Control had a blocking error for more
than 20 hours in a row
Press RESET button to
display the Blocking error

Remove the cause of the Blocking
error
"Fan Error"
12
Fan MF deviation for more than 60 sec
a- Check for 120 Vac power
connection of the fan.
b- Check PWM connection of
the fan.
a- If no 120 VAC voltage is present,
replace the power control board.
b- If no PWM signal is present,
replace power control board.
c- Replace the fan
"Ram Error"
13
Internal software error
Replace the power control board
"Wrong E2prom Signature"
14
Contents of E2prom is not up-to-date
Replace the power control board
"X Ram Error"
15
Internal software error
Replace the power control board
"E2Prom Error"
16
No communication with E2prom
Replace the power control board
"E2Prom Error C"
17
Wrong safety parameters in E2prom
Replace the power control board
"E2Prom Error Cal Table"
18
Wrong calibtration table parameters
Replace the power control board
"State Error"
19
Internal software error
Replace the power control board
"Rom Error"
20
Internal software error
Replace the power control board
"Rom Error C"
21
Internal software error
Replace the power control board
"Air Sw Not Open"
22
Air pressure switch not working
"15Ms Xrl Error"
23
Internal software error
Replace the power control board
"Air Sw Not Closed"
24

“Max. Thermostat Lock Error”
25
The external overheat protection is
activated
a- Check the pump to verify
the flow circulation
b- Check if the valves on
hydraulic circuit are open
c- Check the high limit switch
d- To reset - see Fig. 9
a- Change the pump or restart it
b- Open the valves on hydraulic
circuit
c- Change the high limit switch
"Stack Error"
26
Internal error
Replace the power control board
"Flame Out Too Late Error"
27
