Slave module for
multifunctional, expandable, control units with remote control EV87 and EV90. It
is suitable for all types of centralized sanitary water heat regulation
systems. EV91B is mostly used to regulate sanitary water temperature, but may
be used for fixed point regulation of a generic ambient temperature, of a
greenhouse, a swimming-pool, etc. The device also comes with a useful thermal
disinfection program to prevent legionnaires’ disease.
General Features: Daily programming with 6 ON and OFF schedules;
Sanitary water temperature adjustment from 0 to 100°C; Programming for circuit
thermal disinfection against legionellosis.ù; Parameters visualization and
modification by means of FANBUS from EV90 or EV87 MAS TER; Local programming or
via SMS messages (with GSM modem) or via remote computer (with analog PSTN
modem) via the communication bus (FANBUS) and the MAS TER EV90 or EV87; Addressing
through jumpers on the external terminal board; TX and RX signaling Led for
connection with FANBUS, valve and circulation pump control.
Electric Features: Power supply: 230Vac 50Hz; Consumption: 5 VA; 3
output relays: – 2 for mixing valve control, – 1 for circulation pump control; 1
communication channel FANBUS; 1 analog input to measure collector temperature; Voltage
free contacts; NTC measurement probe type EC15 or EC16.
