Commissioning the system
Commissioning is carried out in 3 stages:
1. Configuring the system
2. Configuring the operating mode
3. Adjusting operating parameters
The parameters and system controller configuration
must be matched individually as required (see follow-
ing chapters and service instructions "Heat pump con-
trol unit Vitotronic SPS, type 2.0").
Note
The type and extent of parameters depend on the heat
pump type and the system configuration.
Observe the instructions in the separate service
instructions of the Vitotronic SPS type 2.0 heat pump
control unit, otherwise the appliance warranty will be
void.
Note
Commissioning must only be carried out by trained
and authorised contractors.
