CONTENT OF DELIVERY AND INSTALLATION

The delivery includes:

1.  Control unit 

2.  Flue gas sensor 

3.  Boiler water sensor

4.  Extension cable

Installation

It is preferable to place the control unit in 

a location where no extension is required 

for the cable of the flue gas or boiler water 

sensors. The extension cable for flue gas and 

boiler water sensor is 4 m long.

1.  Remove control unit lid.

2.  Fluegas fan, loading pump, temperature 

sensors and 230 VAC voltage input are 

connected to the terminal strips under-

neath the control unit lid.

P1=Flue gas fan

P3=Loading pump

T1=Flue gas sensor

T2=Boiler water sensor

T6=Active combustion alert from the pellet 

burner (voltage-free input) 

NOTE: If the pellet burner being used 

cannot supply voltage-free contact data, this 

data can be accessed from the pellet burner’s 

flue gas fan via a supplementary relay. The 

relay should be operable in the voltage area 

100–230 VAC. The fan control unit input is 

controlled by a normally open 

NO

 switch.

Operation mode Wood

When the fan is started in the wood bur-

ning mode, a delay period starts (factory 

setting Fan delay time 15 minutes, can be 

set between 3 and 15 minutes). During this 

delay period, the left top corner of the screen 

displays a figure that tells you how many 

minutes are left of the delay period. 

While the delay period lasts, the flue gas 

temperature will rise above the setting tempe-

rature, and a flame icon will appear inside the 

boiler icon on the screen. The fan will run for 

as long as the flue gas temperature is above 

this limit value (settings Fan temp. limit).
