Electronic boards description
CS176 - Electric supply and relay
The following connection inputs are on the board:
- L/N = Power supply 230 V 50/60 Hz
- OUT 1 = ALARM Relay: Contact in derivation without potential
- OUT 3 = DISINFECTION IN PROGRESS relay without potential
- OUT 2 = RECIRCULATION PUMP relay without potential
(it activates the pump during thermal shock disinfection and when
recirculation programming is active)
Board installation CS179 (optional) on CS180 board
The supply includes 4 screws for correct installation on the 4 spacers
already fitted for on the CS180 board and the multi-pole connection
cable with the CS179 board (RS-485 cable NOT supplied).
CS179 - Data transmission (optional
) code 600001
RS-485 interface MODBUS connection.
An optional memory system allows recording the flow temperature,
return temperature, alarms and functional statuses, useful for
monitoring the operating status of the device. The connection also
allows the remote control of the mixing valve for both parameter
acquisition and modification. The communication is made with the
MODBUS RTU 9600 ON protocol.

IMPORTANT:
When fitting cables for electric connections, be careful not to damage the electronic board components. Every time the regulator-
actuator is removed from the valve it is necessary to perform a new zero acquisition by means of the appropriate control.
Do not disassemble the electronic boards from the appropriate supports.
Do not disassemble the motor.
CS180 - Contacts and probes
The following connection inputs are on the board:
- IN1 = NO (normally open) potential-free contact for
disinfection start-end depending on the mode set
- IN2 = potential-free contact (by default forced in closing by jumper)
for disinfection/thermal shock stop (emergency)
- T1 = Delivery probe
- T2 = Return probe
