Integrative Thermal Source (Krit Accessory) - Hitecsa EWMIM Serie Manual De Instalación, Uso Y Mantenimiento

II.7.12 INTEGRATIVE THERMAL SOURCE (KRIT ACCESSORY)
It is possible to manage an integrative heat source (electrical resistance) from the machine's board.
An integrative thermal source is an electric heater that runs together with the heat pump in winter mode. By means of the unit's control, it is possible to
control start-up and switch-off according to the different variables: outdoor air temperature, delay in reaching the set-point set due to a high thermal
load.
Resistance is always activated during the defrost cycle and when DHW production is requested.
When there is a 3-way valve for KVDEV DHW production, the electrical resistance must be placed upstream of the valve, as illustrated in the figure.
It is always recommended to accurately check the electrical power available when integrative electrical resistances are installed.
