INSTALLATION - PRIMARY CIRCUIT
BOILER SELECTION
• The PremierPlus SystemFit models are suitable for use with most gas, oil fired or electric boilers compatible with unvented
systems i.e. fitted with a temperature control thermostat and thermal cut-out.
• If in doubt consult the boiler manufacturer.
• Solid fuel boilers or any other boiler in which the energy input is not under effective thermostatic control unless additional
and appropriate safety measures are installed should NOT be used.
• The boiler used can either be a sealed system or open vented type, maximum primary circuit pressure 3 bar.
• The primary flow from the boiler MUST be pumped. Gravity circulation will not work due to the special design of the
primary heat exchanger.
• The boiler flow temperature should usually be set to 82°C (maximum flow temperature to primary heat exchanger 88°C).
• The boiler cannot be vented through the PremierPlus SystemFit unit.
INDIRECT THERMAL CUT-OUT AND 2-PORT MOTORISED VALVE
To comply with Building Regulations and to prevent the PremierPlus SystemFit from overheating the 2-Port motorised valve
supplied fitted to the primary flow to the indirect coil MUST NOT be removed or bypassed. This valve is factory wired in
series with the indirect thermal cut-out such that the primary flow to the heating coil is interupted should the PremierPlus
SystemFit unit overheat.
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 PremierPlus SystemFit indirect thermostat and thermal cut-out, primary circulating pump and motorised valves are factory
pre-wired. Further wiring will be required between the wiring centre, the programmer, room temperature sensor and the
boiler (Fig 8, page 17). Additional controls and wiring will be required if a second CH zone is to be fitted to the instalation.
The indirect thermal cut-out MUST NOT be bypassed.
HEATING SYSTEM CONTROLS
The controls provided with the PremierPlus SystemFit will ensure the safe operation of the unit within a central heating system.
Connection to the various system components is made via the wiring centre fitted to the front of the PremierPlus SystemFit,
refer to figure 8, page 17 and the terminal identification labels within the wiring centre to aid in connecting the various
external system components such as the mains supply, programmer and boiler. The wiring to the external components is
made using flexible cable, this should be secured using the integral cable grips located in the wiring centre.
Provision is made for the connection of a second CH zone (connection pipe supplied blanked off). Additional controls will
be necessary to control the operation of the second CH zone, usually a second 28mm CH zone valve and a programmable
room thermostat. Connection terminals are provided and identified in the wiring centre to enable any wiring to be connected
to the same central position.
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 3 amp. A supply cable of 1.0 to 1.5mm
2
cross sectional area should be used.
PROGRAMMER AND ROOM TEMPERATURE SENSOR
The programmer and room temperature sensor are supplied loose such that they can be installed at a convenient location
within the property. These items are supplied with their own installation and user instruction leaflet which should be referred
to for details of mounting, wiring and programming. NOTE: The room sensor is wired directly to the programmer not to the
wiring centre. The room sensor must be used, it is not possible to integrate a standard room thermostat with the programmer.
Temperature setting of the room temperature is also done at the programmer, there is no adjustment at the room temperature
sensor. Temperature setting of the stored water in the PremierPlus SystemFit is done at the indirect thermostat housed within
the indirect terminal housing on the front of the PremierPlus SystemFit unit.
Basic Programmer Features:
• 24 hour or 5/2 day operation
• Room temperature setting at programmer
• Set temperature over-ride facility
• 1 hour hot water boost facility
• Battery back up retains programmed information in the event of a power interuption
• Low temperature set back option for periods when the property is unoccupied, eg. holiday periods
• Independent time control of central heating and domestic hot water (Building Regulation Part L1 compliant)
NOTE: The programmer supplied will only provide control for one CH zone. Should a second CH zone be required, additional
controls will be needed (not supplied) to fulfill the requirements of Building Regulation Part L1.
