Multifunction expandable digital controller for heating systems with remote control, with 4-20mA input-MASTER
-
DESCRIPTION
General features0
EV87 is suitable for the climatic thermoregulation via remote management of all heating systems types.
To control more complex systems, EV87 can be connected to any other controller EV91A-EV91B-EV91C-EV91D-EV92 (defined as SLAVES) by means of a bus called FANBUS. In this case EV87 acts as a MASTER controller.
- Graphical display with 4 lines.
- Software class A.
- RS232 output for modem connection.
- Data storage period: 5 years.
- 6-module DIN housing.
- Two weekly programs with three time bands per day.
- A daily program with three time bands.
- Clock charge lifetime: 5 years.
- Measurement range of external probe: -30..+40°C.
- Measurement range of delivery/limit/auxiliary probe: 0..+99°C.
- Maximum 20 slaves can be connected.
Electric features- Power supply: 230Vac.
- Consumption: 5 VA.
- 4 output relays: mixing valve and pump, boiler with multistage burner (from 2 to 4), boilers in cascade (2 to 4) with choice of main boiler rotation, 2 cascade boilers with two-stage burner with choice of main boiler rotation.
- 2 digital inputs can be used as alarms.
- 1 4..20mA input can also be used to drive the configurable relay.
- 1 output 0..10V (3mA maximum load) with proportional regulation.
- 1 configurable relay (auxiliary probe – 4..20mA sensor).
- Contacts rating: 5A – 250Vca (resistive load).

HOMOLOGATION AND INSTALLATION
Homologation
- Complies with the law 373, law n.10 dated 9 of January 1991 and D.P.R.412 dated 26 of August 1993.
- In conformity with EN 60730-2-9; EN 60730-2-7 standards
- ErP classification: ErP Class VI; 4% (EU Reg. 811/2013 – 813/2013)
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 facilitate the wiring and a possible replacement.
- The EV87 climatic controller is suitable for the thermoregulation with remote management of all types of heating systems and floor-type airconditioning systems. For the thermoregulation of particularly complex systems, the EV87 controller acts as central controller (MASTER) and can be connected to other EV-series controllers (called SLAVE) via a communication bus called FANBUS.
- The EV87 controller can be set as climatic controller for heating system through mixer valve, or for air-conditioning system still through mixer valve or it can be set as fixed point / sliding point / controller for boilers.
