8.4 Boiler control
The Remeha Quinta 30 can be controlled using one of the following methods :
8.4.1 Modulating (two wire control)
When using the optional Broag-Remeha compensating controllers the heat output
modulates between the minimum and maximum value on the basis of the boiler flow
temperature sensor. This applies to both single and multiple boiler installations (up to a
max of 8), under the dictates of a room and/or outside temperature sensor.
Three models of two wire modulating controls are available
- Simple Honeywell Chronotherm Modulation
Single boiler control, compensation based on room temperature, using the Open
Therm interface supplied as std. in the boiler.
Available with 6 adjustable time periods.
Connection via a two-core cable to terminals 1 and 2 of the 24-pole terminal strip.
Installation to be made in a reference room.
Change setting mode parameter ( to 00. Set the x value of the boiler control
operation parameter (A) to 1.
- SR 5240 C1 - Optimising / weather-compensated boiler control for single boiler.
These controls are supplied with outside sensor and mounting kit for installation in
the boiler.
Communication between the Optimising / weather-compensated control and the
boiler control system is via an interface PCB supplied with the kit (to fit see Fig. 17).
Connection via a two-core cable and plug supplied to plug K2 in the boiler.
Installation can also be made in a reference room. In this case, room compensation
can also be applied.
Connection via a two-core cable to terminals 1 and 2.
Set the x value of the boiler control operation parameter (A) to 1.
- 2945 C3 K - Optimising / weather-compensated boiler control for multiple boilers.
These controls are supplied with outside sensor, room sensor, flow sensor (used for
multiple boiler installation only) mounting and wiring kit for installation in the boiler,
see Fig. 16.
Communication between the Optimising / weather-compensated control and the
boiler control system is via an interface PCB supplied with the kit (to fit see Fig. 17).
Set the x value of the boiler control operation parameter (A) to 1.
