7.1.1Heat generator start-up protection

The start-up protection function prevents condensate building up when heating up while cold.

Function There are three different modes of start-up protection that can be set:

Unlimited start-up protection

When the temperature in the heat generator drops to 2 K below the set minimal limit, all heating circuits are separated, at the water side, from the heat generator (pumps = off, mixed heating circuit = closed) to pass through the dew point as quickly as possible. The heating circuits are enabled as soon as the temperature in the heat generator has reached the minimum limit plus half of the burner switching differential 1.

Start-up protection controlled by weather conditions

The heating-up characteristic is the same as for unlimited start-up protection, meaning the heat generator remains in operation until the set minimum temperature plus half of burner switching differential 1 is exceeded. Below the minimum temperature, the pumps remain switched off and the mixed heating circuit closed.

Once the heat generator has been switched off, the start-up protection becomes active again only when the heat generator temperature drops below the weather-responsive demand value (acc. to heating curve setting and nominal room setting). The subsequent heating-up follows the same scheme as for unlimited start-up protection. The result is a mean value based on the difference between the weather condition-controlled demand value and the minimum limit setting. This mean value will be significantly lower than the value set for a heat generator operated with a permanent minimum temperature limit.
