INSTALLATION

17 DHW CONTROL CONNECTIONS

If the boiler is providing both CH and DHW and
the CH circuit is to operate at a reduced
(condensing) temperature, then it is necessary to
differentiate between CH and DHW heat
demands. The boiler will react accordingly by
adjusting the flow temperature and operating
pumps or valves to divert the flow.

A demand for DHW always has priority over CH.
The flow temperature is controlled by PARAs 1 &
B. To limit the boiler output during DHW demand
to match the storage cylinder capacity. See
Frame 21.

1. Tank Thermostat

DHW demand can be controlled with a timer
and/or tank thermostat. Connection to
terminals 7 & 8, with a 24V supply and return,
are available to be switched, open/closed
circuit, by a timer and/or tank thermostat. The
boiler senses open circuit as no call for DHW
and closed circuit as call for DHW. Mains
voltage MUST NOT be applied to these
terminals.

2. Tank Sensor Kit

DHW demand can be controlled using a Tank
Sensor Kit available from Caradon Ideal
Limited. Connection should be made to
terminals 7 & 8, with the boiler automatically
detecting its presence. Full installation
instructions come with the kit. This sensor
has the advantage of providing the boiler with
the actual stored DHW temperature, allowing
closer output matching and reduced cycling.
Use of a tank sensor kit cannot be timer
controlled.

A diverting valve or a separate pump can perform
DHW supply by a storage tank connected to the
boiler. The factory setting is for a pump, but this
can be changed using PARA A. Connection of
the pump or valve should be made via a relay to
terminals 16, 17 & 18.

Note. The terminals 11-13 and 16-18 must be used to control a system pump and a 3-way valve or a DHW pump respectively through
relays as shown above. NEVER supply power directly from these terminals.
