7.2 Adjusting the boiler
▶
During commissioning check:
▪
Maximum possible water throughput is ensured.
▪
Heat up is carried out with low flow temperatures and at low rating.
▪
Operate all boilers on multi boiler systems at the same time at low rating.
▪
Gas connection pressure at maximum rating within range (see Ch. 7.1.2).
1. Configuring the system
▶
Close gas isolating valve.
▶
Switch on system at switch S1 (see Ch. 6.1.1).
On activation of the voltage supply the WTC recognises the boiler type, all connected
sensors and actuators. The recognised configuration is indicated by a flashing display
every 30 seconds.

The configuration is stored.
The display shows

because the gas isolating valve is closed.
If the enter button is not activated within 30 seconds, the configuration will be stored
automatically after 24 hours. The configuration can also be started manually
(see Ch. 6.5). A configured boiler indicates the saved configuration whenever the
power supply is switched on.
The boiler must be reconfigured if sensors or actuators are replaced (see Ch. 6.5).
Automatic configuration is only performed during the initial commissioning.
2. Set parameters
▶
Activate parameter level (see Ch. 6.3).
▶
Select individual parameters and adapt to the requirements of the system.
