Description
Key Installation Benefits
- Relocated flow and return pipework for more intuitive installation connections
- Commonly available components (pumps, valves, standard connections) to improve component supply chain flexibility
- Improved system performance to refine component design
- Footprint template with each model for easier first fix installation
- Hinged flow temperature controller to optimise component access
Features and Benefits
- Unvented plug and play pre-plumbed DHW cylinder will reduce installation time
- Efficient and rapid heating produces excellent hot water recovery times
- Premium quality insulation will reduce heat losses and running costs
- Flexible 2-zone space heating control gives improved comfort and reduced energy use
- MELCloud enabled allows remote control, monitoring, maintenance and technical support
Key Change Points
- Pipework: Flow and Return Connections located behind FTC6. Flow left handside, Return right handside.
- Heat Pump Circuit Pump: Grundfos UPM3L 25-75 – See table below
- DHW Plate Heat Exchanger hydraulic configuration optimised
- Magnetic filter: Fernox TF1 Sigma
- FTC6 Controller: Hinged to allow access to flow sensor
- Flow Sensor: Compression fitting
- Low Loss header: Includes drain off valve
- Diverter Valve: Honeywell V4044C
- Model codes ending with
S = Small = 22mm Pipework - Model codes ending with
L = Large = 28mm Pipework - Footprint of the PH2 cylinders is different
from PH1
