EV87

EXPANDABLE MULTIFUNCTION

CLIMATIC CONTROL UNIT

Employment

The EV87 climatic controller is suitable for the

thermoregulation with remote management of

all types of heating systems and oor-type air-

conditioning systems. For the thermoregulation

of particularly complex systems, the EV87 con-

troller acts as central controller (MASTER) and

can be connected to other EV-series controllers

(called SLAVE) via a communication bus called

FANBUS.

Description

The EV87 controller can be set as climatic control-

ler for heating system through mixer valve, or for

air-conditioning system still through mixer valve or it

can be set as xed point / sliding point / controller

for boilers.

Mixer valve

• 3-way mixer valve control open/close/stop

• Circulation pump control with delayed switch-off

• Auxiliary relay control for a domestic water storage

tank or for a 1-stage boiler

• Delivery temperature regulation according to the

min./max. limit (to be set)

•

Delivery temperature regulation according to the am-

bient temperature read (to be set)

Boilers

Boiler management modes are the following:

• Management of one boiler with 2 or 4-stage burner

• Management of two boilers in cascade

• Management of three boilers in cascade

• Management of four boilers in cascade

• Management of two boilers in cascade with 2-stage

burner

The boiler management provides to set the days of

rotation of the main boiler.

Climatic regulation

The controller calculates the delivery temperature

value at all times as a function of the ambient tem-

perature set, the external temperature read and the

broken regulation curve set. The calculated delivery

temperature can be further regulated through the limit

probe and the ambient probe described in the follow-

ing pages.

Fixed point regulation

It is used to control the boiler. It regulates the delivery

temperature according to a xed temperature value to

be set.

Sliding point regulation

It is used to control the boiler. The EV87 controller, via

FANBUS, acquires the delivery temperature required

by each connected SLAVE module. The max. tem-

perature value required is added to the temperature

value set thereby obtaining a variable boiler tempera-

ture control according to the system requirements.

The EV87 controller features two digital inputs to be

used as alarms. Furthermore a serial line can be con-

nected to a modem, thus enabling the control unit to

transmit any system fault to a remote station (e.g.:

mobile phone or PC), and to be remotely managed

using SMS messages or DATA transmission.

Broken regulation curves

The EV87 controller has a winter curve and a sum-

mer curve to be used to calculate the delivery tem-

perature. The curve is selected through the heating

period and the cooling period set. Both curves rep-

resent the delivery temperature as a function of the

external temperature to obtain 20 °C ambient tem-

perature, and are used for climatic regulation.

To obtain different ambient temperature values, the

broken regulation curve moves along the line +Ta..-

Ta. The relation that establishes the delivery temper-

ature value as a function of the external temperature

depends on the thermal properties of the building

and, for optimum comfort, must be found by experi-

menting.

N.B. In systems with panels, limit the delivery

temperature values to max. 45°C.
