Technical data

52 i-KI MTD / i-KIR MTD EN 10/2010
SYSTEM CONFIGURATION
U I A
Heat pump connection to the system without low-loss header. Make sure the useful pressure head of the circulating
pump on the unit is sufficient for the pressure drop in the system. If the minimum system content does not reach val-
ues shown in this manual, install an additional storage tank on the heat pump return pipe. No system configurations
are required.
For installations with heap pump connected directly to the system, without storage tanks and secondary pumps, parameter
011D must be set to 0. This means that heat pump operation will be managed based on the time bands.
