PRIORITY DHW CONTROL
TEMPERATURE CONTROL
With a Remeha temperature sensor or with a standard (volt free)
DHW thermostat.
Note: It will only provide a setting and read out facility when the sensor
option is used.
Primary flow control:
•
with a 3-way diverting valve (not Q90/115)
•
with a DHW pump
•
untimed (available 24 hours a day).
SYSTEM/SHUNT PUMP
A shunt pump can be connected to the boiler (maximum input
200w). If the pump requires more than this, terminals can only
be used to switch a pump relay. The pump should be fitted on
the heating return connection and be as close to the boiler as
possible. A system pump can also be connected to the boiler
via SCB - 01 (Refer to page 24, SCB-01 Relay Load data for
maximum load).
SYSTEM WATER
Before operation, the system should be cleaned and flushed
(according to BS 7593 (2006), and filled with mains cold water.
Suitable chemicals and their use should be discussed with
specialist water treatment companies in respect to aluminium
heat exchangers. For further information “Remeha Water
Quality Regulations” is available from
remeha.co.uk
The recommendations in the document must be followed.
FROST PROTECTION
Install the boiler in a frost-free room. The built-in frost protection
system is activated as follows: below 7°C – system pump is
switched on if connected to the boiler. Below 3°C – boiler is
switched on, when the flow temp reaches 10°C the boiler and
pump switch off.
Note: This control is designed to protect the boiler – for full system protection
use a frost thermostat or a weather compensator.
REMOTE ALARM AND
BOILER RUN INDICATION
As standard the boiler is supplied with the integral smart
control board SCB-01. This has two potential-free contacts,
Status / Function, can be configured as required. Depending
on the setting, a common alarm and boiler run signal can be
transmitted by the boiler.
SAFETY INTERLOCKS
As standard the boiler is supplied with shutdown (BL)
and release (RL) inputs via the main standard connections
board CB 03.
