TABLE 11.1 ELECTRICAL SUPPLY REQUIREMENTS
WARNING: THIS APPLIANCE MUST BE EARTHED
A suitably competent person MUST check wiring. Normal supply required is 230 volts AC, single phase,
50 Hz. An isolator with a contact separation of at least 3mm in all poles should be sited close to the
equipment and must only serve that equipment. The double pole switch must be readily accessible under
all conditions.

Outside
Temperature
Sensor
When an outside temperature sensor is connected, the boiler setpoint will be compensated in relation to the
outside temperature. The addition of this sensor will reduce the flow temperature of the boiler in warmer
temperatures, increasing energy efficiency.
A change in control parameters will be required when this sensor is connected and the control system should
be configured to function as required. For further information, please refer to
Section 12.10: OUTSIDE
TEMPERATURE COMPENSATION .

Cascade Flow
Temperature
Sensor
When a multiple boiler cascade is used, the master boiler requires a flow sensor to be fitted to the common
pipework in order to control the firing rate whilst acting as a “lag” boiler.
The sensor should be located on the system flow adjacent to the low velocity header.
No change in control parameters will be required when this sensor is connected.
5-6
Calorifier
Sensor or
Thermostat
Where a DHW calorifier is used, a hot water sensor or an on/off thermostat can be connected. When a
sensor is connected, the water temperature will be shown on the display; when a thermostat is used the flow
temperature to the indirect storage vessel will be shown.
7-8
General
Blocking
Where an interlock with a safety system such as a flue fan or mechanical ventilation system is required, the
safety circuit should be wired to terminals 7 and 8. Where more than one safety system is used, each system
should be wired in series.
When the link on 7 and 8 is broken, all heat demands, including frost protection are blocked.
9-10 Empty N/A
11-12
External Water
Pressure
Switch
A water pressure sensor is mounted in the boiler with a maximum pressure of 4.0 bar. As an option, the
sensor can be replaced by a water pressure switch, which can be wired to the terminals. When terminals 11-
12 are not bridged, the boiler will lock-out.
A change in control parameters is required to activate this function.
