All inputs MUST be Volt-free/ Connected via Volt-free Relay
SW1-7 MUST BE ON = Monobloc Heat Pump In Use SW2-8 MUST BE ON = Flow Sensor In Use
The guidance below applies to the FTC6 (Indoor Unit). Turn ON relevant DIPS as shown below, all remaining DIPS to be OFF.
FTC6 Commissioning GUIDE
For Single Heat Pump / Basic Applications OnLY
After completing the commissioning wizard, go into Initial Settings and set the Room Sensor Settings: • If using Mitsubishi Electric Wireless Room Stat(s), select Room RC. • If using the Main RC itself, 3rd-Party Room Stat or Underfloor Wiring Centre, select Main RC.
Room Sensor Settings
SW1-8 ON = Mitsubishi Electric Wireless Room Stat(s) In Use. (Maximum of 8) SW2-1 ON = 3rd-Party room stat or underfloor wiring centre controlling Heating Zone 1 via IN1 SW3-1 ON = 3rd-Party room stat or underfloor wiring centre controlling Heating Zone 2 via IN6 SW5-2 ON = Advanced Auto Adaption Mode Active (Only compatible with Mitsubishi Electric wireless room stats)
Heating Controls
SW3-5 ON Only = Single Heating Zone SW3-5 & SW3-6 ON = 2x Heating zones with the same flow temperature SW3-5, SW2-6 & SW2-7 ON = 2x Heating zones/ different flow temperatures/ FTC controlling blending valve for zone 2 only
Heating Mode
Essential Settings
SW1-3 ON = Domestic Hot Water Mode Active SW1-4 ON = FTC to control Immersion Heater for Legionella prevention and as back-up if an error occurs SW3-7 ON = Mitsubishi Electric Pre-plumbed Cylinder In Use. (Leave SW3-7 OFF for Coil Cylinders)
Hot Water Mode
Top of FTC6 PCB
Please note: When SW2-6 & SW2-7 are ON (2x Heating Zones with different flow temperatures), additional temperature sensors are required for each heating zone. Description: Flow & Return Temperature Sensors 5m Cable Model Name: PAC-TH011-E Reference Code: 258695
Heating Circuit Configurations
Power Supply Configurations
1x Dry pocket is required for Mitsubishi Electric hot water temperature control thermistor THW5B, connected via Blue Plug CNW5 / 3 & 4.
At least one immersion element is required to connect to the FTC board to comply with G3 regs
A coil with suitable surface area for low temperature heat pumps
If the installation is in a hard water area or more than 250mg/L calcium hardness, a scale reducer must be fitted
All safety devices and pipework should be accessible for annual service and inspection
Must be high density injection or spray on foam insulation to current building regulations
Diverter valve needs to be full-bore full diverter (NOT a Mid-position Valve)
Only 1x hot water cylinder may be used - Must be indirect
