8.4 Boiler control

The Remeha Quinta 115 can be controlled using one of the following methods:

8.4.1 Modulating controls general (two wire control)

To make full use of the boiler's modulating feature, an OpenTherm
connected. These controls will provide optimised time and weather compensation to
achieve maximum efficiency and minimum boiler cycling whilst maintaining design
condition within the building.
Modulating single boiler controller
Single boiler control, compensation based on room temperature, using the
OpenTherm interface supplied as std. in the boiler.
Available with 6 adjustable time periods.
Celcia 20 - An optimising/ weather-compensated boiler control for single boilers.
This compensator can regulate the boiler output against outside weather conditions,
and provide time and temperature control over the DHW. The compensator is
mounted in a reference room (uses an internal sensor to monitor room temperature)
and is interfaced to communicate with the boiler's controls via a two-core cable to
terminals 1 and 2 of the 24-pole terminal strip. On site connection of the supplied
outside and common flow sensors complete the installation.
