Designed for wall-mounting with connections in top and bottom of substation. The temperature for the heating circuit is controlled by a Danfoss ECL 110 controller in combination with an electronic actuator. The supply temperature is calculated by the controller on basis of the outdoor temperature. - Page 21 DHW temperature control Danfoss PTC2+P controller (1) for DHW. The DHW temperature is adjusted by turning the lever towards “+” (warmer) or “-” (colder). Start by turning the handle clockwise - until stop /until the handle can not be turned anymore.
