1. Fill the appliance

.

2. Open

 the manual gas 

valve.

3. Switch on the power to the appliance using the 

isolator between the appliance and the power 
supply. 

4. Switch the electronic controller ON by setting the 

ON/OFF switch to position I.

The appliance is now in "ON mode". If there is a 
heat demand, the appliance will run through the 
heating cycle

If the heating cycle is not run, then there is no 
demand; should this happen, then Tset will 
probably need to be set

The appliance's heating cycle is activated as soon as 
the measured water temperature (T

net

) falls below the 

threshold value (T

set

). This threshold value depends 

on the currently selected appliance operating mode. 
For example, if the appliance is in "OFF mode" (frost 
protection), then this value is 5°C. If the appliance is in 
"ON mode", then this threshold value is selectable, for 
example, 65°C.
The heating cycle runs in turn through the following 
states:
1. HEAT DEMAND;
2. PRE-PURGE;
3. PRESSURE SWITCH;
4. PRE-GLOW;
5. IGNITION;
6. RUNNING;
7. POST-PURGE.
