dTSH sets the temperature difference between the actual room temperature (Ta) and set room temperature (TS) above
which the heat pump provides hot water to the space heating terminals. When TS – Ta ≥ dTSH the heat pump provides hot
water to the space heating terminals and when Ta ≥ TS the heat pump does not provide hot water to the space heating
terminals. dTSH is only relevant if YES is selected for ROOM TEMP in the 5 TEMP. TYPE SETTING menu.
