Hot Water Mode

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 occursSW3-7 ON = Mitsubishi Electric Pre-plumbed Cylinder In Use. (Leave SW3-7 OFF for Coil Cylinders)

Essential Settings

Heating Mode

SW3-5 ON Only = Single Heating ZoneSW3-5 & 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 Controls

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)

Room Sensor Settings

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.

FTC6 Commissioning GUIDE

The guidance below applies to the FTC6 (Indoor Unit). Turn ON relevant DIPS as shown below, all remaining DIPS to be OFF.

SW1-7 MUST BE ON = Monobloc Heat Pump In UseSW2-8 MUST BE ON = Flow Sensor In Use

All inputs MUST be Volt-free/Connected via Volt-free Relay

Power Supply Configurations

Heating Circuit Configurations

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

3rd-Party Cylinder Specification

Only 1x hot water cylinder may be used - Must be indirect

Diverter valve needs to be full-bore full diverter (NOT a Mid-position Valve)

Must be high density injection or spray on foam insulation to current building regulations

All safety devices and pipework should be accessible for annual service and inspection

If the installation is in a hard water area or more than 250mg/L calcium hardness, a scale reducer must be fitted

A coil with suitable surface area for low temperature heat pumps

For cylinders that have a coil heat exchanger and 1x DHW Temperature Sensor = DIP Switch SW3-7 on the FTC Board MUST be OFF.

At least one immersion element is required to connect to the FTC board to comply with G3 regs

1x Dry pocket is required for Mitsubishi Electric hot water temperature control thermistor THW5B, connected via Blue Plug CNW5 / 3 & 4.

For cylinders that have a coil heat exchanger and 1x DHW Temperature Sensor = DIP Switch SW3-7 on the FTC Board MUST be OFF.

The water in both primary and DHW circuits should be clean and with a pH value of 6.5 to 8.0 The following values should not be exceeded in the water supply conditions: Calcium: 100mg/L Ca hardness: 250mg/L Chlorine: 100mg/L Chloride: 100mg/L Copper: 0.3mg/L Iron/Manganese: 0.5mg/L In known hard water areas, to minimise any scaling the stored DHW temperature should be restricted to 60oC

How to create additional heating circuits

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. Part Required Description: Flow & Return Temperature Sensors 5m Cable Model Name: PAC-TH011-E Reference Code: 258695
