Instructions to utilise the remote BMS On function on a MC200V3
To utilise the remote BMS ON function on a MC200CV3 you must set it up as below:
Wire a two core cable on terminals ‘SEN 2’ and ‘COM’. Take the other ends to a volt free - normally open switch or Relay.
Alter preset programme in the MC200 to read the following: Heat On at 00:05; Heat Off at 23:55; P1 : 7 days
Alter ‘Snsr2’ parameter within Engineers menu of the MC200 to read: Open=off
When the circuit is open (i.e. timer not in operation) the display will read “P1 REMOTE OFF” and heater will not fire. When this circuit is closed (i.e. Push Button Timer pressed) the display will read “P1 HEAT ON” and heater will fire.
