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 îš¿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 îš¿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.
