Evoplus SMALL Multifunction module (Revision N. = 2)

This module can activate the specific mode of the Evoplus:
Constant and proportional differential pressure control mode depending on water temperature.

The circulator head set-point is reduced in accordance with the water temperature.
Liquid temperature can be set from 0°C to 100°C.

This control mode is particularly useful in the following types of installations:
a. - in variable flow rate installations (two-pipe central heating systems), in which a further reduction of circulator performance is provided in accordance with lowering of the circulating liquid temperature, in the presence of reduced heating demand.
b. - in constant flow rate installations (single-pipe and under-floor central heating systems), where the performance of the circulator can be adjusted only by activating the temperature influence function.
This function is set on EVOPLUS control panel.
