By accessing this parameter and turning knob “5” (Figs 1 and 2 - page 4), the curve can be shifted in a parallel manner. The value is indicated on the display, from -20 to +20. 4 2 4 Room sensor Influence to calculate the from 0 to 20 20 set-point temperature - Thermoregulation If set to = 0 the room temperature doesn’t influence the calculation of the set-point. enabled- If set to = 20, the room temperature has the maximun influence to calculate the setpoint - only active when the BUS device is connected 4 2 5 Maximum Central Heating Temperature Zone1 from 40 to 82 (°C) 82 4 2 6 Minimum Central Heating Temperature Zone 1 from 40 to 82 (°C) 40 4 3 DIAGNOSTICS 4 3 0 Room Temperature Zone 1 - only active when the BUS device is connected 4 3 1 Flow Temperature Zone 1 - only active when the BUS device is connected 4 3 2 Zone 1 Heat Request 0 = OFF 1 =ON 4 3 3 Zone 1 Pump status 0 = OFF 1 =ON Active only with MGZ/MCM Kit 4 4 ZONE 1 DEVICES 4 4 0 Zone 1 Pump control 0 = OFF 1 =ON Active only with MGZ/MCM Kit 5 ZONE 2 PARAMETER 5 0 ZONE 2 SET TEMPERATURE 5 0 0 Set Day Temperature Zona 2 from 16 to 30 (°C) 19 only active when the BUS device is 5 0 1 Set Night Temperature Zona 2 from 16 to 30 (°C) 16 connected 5 0 2 Fix temperature central heating from 35 to85 (°C) 70 To set only with Fixed Flow Temperaure of Thermoregulation (see 521) 5 1 Service code 222 Press +/- to select code 234 and press 5 2 SET ZONE 2 5 2 0 Zone 2 Temperature range DO NOT MODIFY 0= Low Temperature 1= High Temperature 5 2 1 Select Type of Thermoregulation 0 = Fixed Flow Temperature 1 = Basic Thermoregulation 2 = Room Temperature only 3 = Outdoor Temperature only 4 = Room + Outdoor Temperature MENU/OK ONLY FOR SERVICE Active only with MGZ/MCM Kit 1 To enabled thermoregulation press Auto button.
