TEMPERATURE REGULATION MODULE
WITH OUTSIDE PROBE
temperature and the outside temperature. The re-
quired ambient temperature is set by the user through
a conguration menu shown on the MASTER EV90
display, and it may take on various values depending
on the selected program.
culates the WATER DELIVERY TEMPERATURE
required to obtain the ambient temperature associa-
terpolation by using the values set for water delivery
temperature for four outside temperature values
( 20°;10°; 0°;-10°).
This curve represents the water delivery temperature
values based on the external temperature required to
obtain an ambient temperature of 20°C.
For other ambient temperatures, the broken regula-
tion curve moves along the straight line “+Ta -Ta”.
The EV91A module works properly only when it is
connected through a two-wire serial bus (FANBUS)
bitrates bus data and checks the conditions of all de-
vices connected to it.
The EV91A module receives from the MASTER con-
trol unit all information required to perform regulation
like: time, current date, etc.
USE
The EV91A module is suitable to be used on all types
of centralised heating plants like those installed in
housing estates, schools, hospitals, factories, etc.
Each setting may be controlled by a temperature
regulation module of the EV91A type for a maximum
of eight rooms.
The EV91A module enables to fully manage a mixing
valve, a circulation pump and an auxiliary output.
OPERATION
The EV91A is designed to obtain a certain AMBIENT
