Duct T Limit / Room Limit - Danfoss ECL Comfort 210 Installation Manual

Installation Guide

5.3 Duct T limit / Room limit

The following section is a general description for Duct temperature
limitation and Room temperature limitation.
The actual application might not have both limitation types.
This section is only relevant if you have installed a duct / room
temperature sensor or a Remote Control Unit for utilizing the room
temperature signal.
In the following description is referred to "flow temperature" in
general. This can be air duct or inlet temperature too.
The controller adjusts the desired flow temperature to compensate
for the difference between the desired and the actual duct / room
temperature.
If the duct / room temperature is higher than the desired value, the
desired flow temperature can be reduced.
The 'Infl. -max.' (Influence, max. duct / room temp.) determines
how much the desired flow temperature should be reduced.
Use this influence type to avoid a too high duct / room temperature.
The controller will allow for free heat gains, i.e. solar radiation or
heat from a fire place etc.
If the duct / room temperature is lower than the desired value, the
desired flow temperature can be increased.
The 'Infl. -min.' (Influence, min. duct / room temperature)
determines how much the desired flow temperature should be
increased.
Use this influence type to avoid a too low duct / room temperature.
This could e.g. be caused by windy surroundings.
A typical setting will be -4.0 for 'Infl. -max.' and 4.0 for 'Infl. -min.'
Some parameter descriptions refer to "duct temperature" because
the parameter in question is used in other applications too.
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.
