Test Operation Function; Forced Maximum / Minimum Combustion Function; Current Proportional Range Compensation - Saturn KDB - 161 GOM Manual

4.18.2.26 Test Operation Function

- It is priority of the set function of DIP switch.
- Pump operates for 2 hours. In case of open type, operate continuously after auto water filling when low water level is
happens.
- If releases test operation by manipulating DIP switch in standby status after performing test operation and sets again,
initializes test operation function and starts test operation.
- When low water level (pseudo flame) happens in case of closed air type, releasing automatically by the interval of one
minute and progresses continuously.
- When flow switch is ON in case of closed air type, stops pump and checks trouble.
- When DIP switch sets test operation, the power lamp flickers by repetition of ON for 1 second and OFF for 1 second.

4.18.2.27 Forced Maximum / Minimum Combustion Function

- When change-over switch sets to forced Max or forced Min, combusts by the set Max or Min according to the capacity
of the boiler after normal ignition. (PID control doesn't.)
- When DIP switch sets for both forced Max and Min at the same time, combusts by forced Min.
- During combustion of forced Max / Min, operation of stopping time isn't performed.
- If the test operation is ON in status of forced Max/Min operation, the function of forced Max / Min operation isn't work.

4.18.2.29 Current Proportional Range Compensation

- Maximum current change by adjusting variable resistor for maximum current compensation.
- Current compensation range can be variable more than ± 20mA of maximum current.
4.18.4.30 The Others
- Heating flow switch is used to monitor water level of closure type (closed air type).
- Power lamp is always lit in the condition of power ON and flickers by the repetition of ON for 0.5 second and OFF for 0.5
second in the abnormal condition.
