HOMOLOGATION AND INSTALLATION
Homologation
- Complies with EN60730-1 standards.
Installation and use- DIN-rail mounting (6 modules).
- To ensure an adequate protection install the device on the DIN-rail within a framework.
- The removable terminals simplify the wiring and a possible replacement.
- The EV40 differential control unit is suitable for the regulation and control of thermal solar panel systems, both of the vacuum tubes and flat plate types, with fluid forced circulation.
- It is able to control both heating and cooling of the environment through the management of the systems with solar cooling. Eight system types are available, according to the specific required application.
- The control unit is fitted with three analogue inputs for temperatures reading (from 0 to 150°C), and with two relays operating the solar pump. If required, it can be fitted with another electromechanical actuator which will be different according to the type of selected system.
- A third relay can be programmed to cover different auxiliary functions, for example, the integration of the boiler electrical resistance.
- Furthermore, EV40 control unit can be linked to an EM70 modem in order to remotely program and manage the system using SMS messages, or just to know its current status.
