8.4 Boiler control

The Remeha Quinta 85 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
OpenTherm 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.
