6.  Power/status light. 

 

Steady glow:

Normal operation.

One long 

one short flash:

Power staging is limited by delayed 

reconnection after a power cut.

One long 

two short flashes:

Power staging is limited by the load guard, 

the room thermostat or other external 

control.

One long 

three short 

flashes:

A. Excess temperature: the power will be 

reconnected when the temperature has 

fallen.
B. Faulty temperature sensor: you must 

replace the sensor before running the 

boiler. To cancel the alarm, disconnect the 

boiler for 10 seconds.

One long 

four short flashes:

Remote control activated.

Rapid flashing

Bypassed delayed reconnection – 

"SNABB" [FAST] button pressed.

Off:

No power (switch set to position O with 

UTK E)

8.  PCB. 

The power is controlled with binary logic, which means that the 

three power groups are connected as in the table below.

9.  Indicator for power group one.
10. Indicator for power group two.
11. Indicator for power group three.
24. Temperature setting with remote control.
25. Switch for external block/remote control. See External block and 

remote control, page 6.

26. Button to temporarily disable delayed reconnection after power 

failure and to speed up the connection of power stages. 

According to the standards, no more than 50% of the power can 

be connected immediately after a loss of power lasting longer 

than three minutes. The remaining power is delayed by an hour.  

To test the boiler after it has been without power, for example 

during installation or servicing, the delayed reconnection can 

be disabled temporarily by pressing and holding the "SNABB" 

[FAST] button until the status light stops flashing. 

You can use the "SNABB" [FAST] to speed up the connection of 

power stages for testing. Keep the button pressed for as long as 

you need. The power may be limited by the load guard or by the 

excess temperature protection.

27. Switch for setting operating parameters:

28. Relay outputs for power group one.
29. Relay outputs for power group two.
30. Relay outputs for power group three.
31. Output for circulation pump with summer mode/eco function 

– the pump stops eight hours after the last time a power stage 

is connected. The pump is operated briefly every twelve hours. 

For best results, use UTK E to control the boiler. See point 27,
