INSTALLATION AND OPERATING INSTRUCTIONS
Problem
Possible Cause
Suggested Remedy
System or Boiler Overfilling or Flooding
(Steam Boilers)
New boiler water content smaller than old boiler
Install Boiler Feed System with Receiver Tank
Large enough for Condensate
Boiler water feed rate or pump rate too fast
causing water level to collapse (due to collapse of
steam bubbles in boiler water)
Reduce Feed Rate
Foaming, priming or surging due to poor
water quality
Clean the Boiler
Excessive Water Level Bounce
(Steam Boilers)
Poor water quality, causing foaming and surging
Clean the Boiler
Incorrect near-boiler piping, such as undersized
or incorrectly placed risers
Pipe per Manual
Boiler water feed rate or pump rate too fast
Reduce Feed Rate
Rapid Cycling
(Steam Boilers)
Air vents or traps not venting air, preventing
steam from getting to radiation and pressurizing
the air pocket
Replace Vents or Traps
Pressure differential on pressure control too close
Adjust Control Differential
Nuisance outages of water level control due to
boiler water level bounce
See Excessive Water Level Bounce Above

Table 10.2: Capable Controls Series 5 Ignition Module – Sequence of Operation and Error Codes
Trial for Ignition
– 90 seconds, 5 minute wait between trials for ignition.
LED Indications, Normal Operation
Green, blinking rapidly
Trial for ignition
Green, on solid
Flame detected, pilot/main burners on
Green, 1/2 sec on, 1/2 sec off
Wait time between trials for ignition
LED Indications, Error Operation
Upon detection of a fault by the ignition module’s internal diagnostics, sparking is turned off and pilot and/or main gas valve(s) are closed.
See LED error codes below. To reset module and clear error, interrupt call for heat (power).
Red Flashes
Error Definition
Suggested Remedy
1 flash
N/A (non-retry models only)
Not applicable
2 flashes
Flame sense stuck on
If pilot lit with all power off, replace gas valve. Otherwise, replace module.
3 flashes
Pilot/Main relay failure
Replace module
4 flashes
Repetitive flame loss error
Check gas pressure, flame size, electrode position.
5 flashes
N/A (models with flame rollout)
Not applicable
6 flashes
N/A (models with APS sensor)
Not applicable
7 flashes
Internal control error
Replace module
Solid Red
Line Voltage/Freq Error
Verify voltage and frequency of incoming power.
