1INTRODUCTION
1.1 Introduction
EV3 HP and EVD HP are controllers for reversible air-water and
water-water single-circuit residential heat pumps.
EV3 HP is available in the standard 74x32mm 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.
These controllers are capable of running compressors and fans
of both the on-off and modulating types.
EV3 HP is available with a 12VAC power supply, while EVD HP
can be supplied with a 115... 230VAC 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.

3.4 Installation precautions
- Ensure that the working conditions for the devices (operating temperatures, humidity, etc.) are within the set limits. See
the section TECHNICAL SPECIFICATIONS.
- Do not install the devices close to heat sources (heating elements, hot air ducts, etc.), equipment with a strong magnetic
field (large diffusers, etc.), in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or shocks.
- In compliance with safety regulations, the devices must be installed properly to ensure adequate protection from contact
with electrical parts. All protective parts must be fixed in such a way as to need the aid of a tool to remove them.

4.3 Fitting the termination resistor to the RS-485 MODBUS slave port
To reduce reflections on the signal transmitted along the cables connecting the devices to a RS-485 network it is necessary to fit a
termination resistor to the first and last element in the network.
To fit the EV3 HP termination resistor, place micro-switch 1 in position ON. Do not touch micro-switch 2.
To fit the EVD HP termination resistor, place micro-switch 1 in position ON.
