EV3 HP & EVD HP

EV3 HP and EVD HP are controllers for:
  • reversible air-water single-circuit residential heat pumps
  • water-water single-circuit residential heat pumps.
EV3 HP is available in the standard 74x32 mm format with built-in user interface consisting of a double custom display, with decimal point and function icons, and four touch keys. It guarantees IP65 protection for easy cleaning.

EVD HP is available in standard 4-module DIN format, in a blind version that can be connected to a remote user interface (EV3K01) if required.

For managing the circuit of a DHW tank and of solar panels it is necessary to use an I/O expansion (EVD EXP).

These controllers can run compressors and fans of both the on-off and modulating types.

EV3 HP is available with a 12 VAC power supply, while EVD HP can be supplied with a 115... 230 VAC power supply.

EV3 HP is designed to be installed on a panel with snap-in brackets, while EVD HP is fitted to a DIN rail in a control panel.
