EV3914 PARAMETRIC CONTROLLER

MAIN HARDWARE DETAILS
 
12 V controller with 74x32 mm dimensions.  
 
4 Digital outputs (configurable 3A),10 Inputs (3 digital inputs (configurable)+7 digital/analog inputs (configurable) ), 2 Analogue outputs (0-10 V/PWM/phase cut)
 
USER INTERFACES AVAILABLE ARE;
 

EV HPRU is a series controllers with ready-to-use application software for running reversible air-water and water-water singleor double-circuit residential heat pumps with up to 6 compressors.
These controllers are capable of running compressors and fans of both the on-off and modulating types. The models equipped with 2 Triac outputs can directly manage fan speed and external solid state relays.
Inputs and outputs number can be further increased through an expansion module, allowing the management of the second circuit and that of a DHW tank and of solar panels.
The solution is available in the following hardware formats: - EV3 (74x32mm) with built-in LED display, capacitive touch keys, IP65 front protection, 12 VAC power supply and panel fitting; - EVD (4 DIN modules) in blind version or with built-in LED user interface, 115... 230 VAC power supply and DIN rail installation. Both formats can be connected, according to your needs, to the stylish panel- or wall-mounted interface EVJ LCD or to Vled 3, a reduced-depth interface for panel fitting.
