Priority DHW control
Temperature control
With a Remeha temperature sensor or with
a standard (volt free) DHW thermostat.
Note: will only provide a setting and read out
facility with the sensor option.
Primary flow control
- With a three-way diverting valve. (Not
Q85/115)
- With a DHW pump.
- Untimed (available 24 hours a day).
System pump
A system pump can be connected to the boiler
(230-1-50 max. 1 amp). If the system pump
requires more than 1 amp, terminals can only be
used to switch a pump relay.
System water
Before operation the system should be flushed
and filled with mains cold water. As the heat
exchanger is aluminium, if water treatment is
considered a max. pH level of 8.5 MUST NOT BE
EXCEEDED. Remeha recommended treatments
are - Sentinal ‘X-100’® or Fernox F1®.
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 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
themostat or a weather compensator.
Remote alarm and boiler
run indication
As standard the boiler is supplied with 2 x volt
free indicators - Common alarm signal (opens on
alarm) and boiler run signal (closes on Boiler
run). Maximum 230 volts, 1amp capacity each.
Safety interlock
As standard the boiler is supplied with an
interlock carrying a 24 volt boiler control circuit.
