10 Settings Live Operating description Heating only. When the DP120 differential is reached, domestic hot water production is triggered. If there is not enough domestic hot water (e.g. if the domestic hot water does not heat up quickly enough): reduce the trip differential (hysteresis) by modifying the value of the DP120 parameter. The DHW tank will then heat up the water more quickly. -
