proportional heating band

: neutral zone
The PI heating controller controls the heating valve, taking the following control parameters into account:
• supply temperature,
• supply set - neutral_zone (
123
) / 2,
• proportional band for heating supply control
114
• integral control time for heating supply
115
.
If the temperature of the supply sensor is lower than the supply set -
12
3 / 2, the heating output valve (or modulating
resistance) is active, the
(or
) icon is displayed.
The
(or
) icon switches off when the output of the heating slave PI controller is equal to 0.
The heating valve can be controlled with PI action if the integral time
115
does not equal 0, or with proportional action only
if
I15
=0.
Control with a single cooling valve:

:
proportional cooling band
123
: neutral zone
The PI cooling controller controls the cooling valves, taking the following control parameters into account:
• supply temperature,
• supply set + neutral_zone (
123
) / 2,
• proportional band for cooling supply control
116
• integral control time for cooling supply
117
.
If the temperature of the supply sensor is higher than the supply set +
123
/ 2, the cooling output valve is activated, and the
icon is displayed.
The icon switches off when the output of the cooling slave PI controller is equal to 0.
The cooling valve can be controlled with PI action if the integral time
117
does not equal 0, or with proportional action only
if
117
=0.
