MAIN CONTROLLER FLOW RATE LOOK UP

The main controller can now show you the flow rates by using Request Code 540 in the Service Menu (see FTC5 main manual).

WIRING

All electrical wiring should be carried out by a competent electrician and be in accordance with the latest I.E.E. Wiring
Regulations.
The Pre-plumbed cylinder thermal controls, primary circulating pumps are factory pre-wired. Further wiring will be required
between the FTC5 controller, the programmer, room temperature sensor and the Heat Pump. Additional controls and wiring
will be required if a second CH zone is to be fitted to the instalation.
Any thermal controls and over-temperature thermal cut-outs MUST NOT be bypassed.
The mains supply must be via a double pole isolating switch with a contact separation of at least 3mm in both poles. The
supply must be fused 10 amp. A supply cable of 1.0 to 1.5mm
THIS APPLIANCE MUST BE EARTHED

HEATING SYSTEM CONTROLS

The controls provided with the Air Source Heat Pump pre-plumbed cylinder will ensure the safe operation of the unit within
a central heating system.
Connection to the various system components is made via the FTC5 Controller fitted to the front of the Pre-plumbed cylinder,
refer to the Manual supplied for the FTC5 Controller and the terminal identification labels within the FTC5 Controller to aid
in connecting the various external system components such as the mains supply, programmer and heat pump. The wiring
to the external components is made using flexible cable, this should be secured using the integral cable grips located in the
FTC5 Controller.
Provision is made for the connection of a second CH zone (connections supplied blanked off). Additional controls will be
necessary to control the operation of the second CH zone. Connection terminals are provided and identified in the FTC5
Controller to enable any wiring to be connected to the same central position.
