DAB Evoplus Small Multifunction Module for Pumps from N.3

Evoplus SMALL Multifunction Module (Revision No. > 2) This module enables the following specific operating mode of the Evoplus: Constant and proportional differential pressure control depending on the water temperature. The head of the circulation pump is reduced according to the water temperature. The fluid temperature can be set from 0 °C to 100 °C. This control mode is particularly useful in the following types of systems: a. - in systems with variable flow (two-pipe district heating systems) where the circulation pump output is further reduced when the fluid temperature drops and heating demand is reduced. b. - in systems with constant flow (single-pipe and underfloor heating systems) where the circulation pump output can only be adjusted by activating temperature control. This function is set on the Evoplus control panel.
