Explanation
El Heating 2
Additional electric heating register with control type.
No
No additional electric heating register available.
Analog
Additional electric heating register with control via an analog out-
put.
1Step
Supplemental, 1-step electric heating register with control via one
analog and one digital output.
2Steps
Supplemental, 2-step electric heating register with control via one
analog and two digital outputs.
3Steps
Supplemental, 3-step electric heating register with binary encoded
control via one analog and two digital outputs.
Cooling 2
Additional cooling register with type.
No
No additional cooling register.
Water
An analog output for the additional water register valve.
DX 1Step
One analog and one digital output for 1-step control of an addi-
tional direct expansion evaporator.
DX 2Steps
One analog and two digital outputs for 2-step control of an addi-
tional direct expansion evaporator.
DX 3Steps
One analog and two digital outputs (binary) for 3-step control of an
additional direct expansion evaporator.
Fire damper
Fire dampers
No
No fire dampers.
Yes
One digital output and input each for fire damper control.
FollowUnit
One digital output and input each for fire damper control. In this
case, damper opened with Unit Start or closed with Unit Stop. This
setting only makes sense when the damper also uses shutoff de-
vice.
Configuration 1
This parameters enable the plant after successful parameteriza-
tion. Enable occurs when Configuration 1, Configuration 2 and
Configuration IOs are completed, i.e. when each has the value
"done".
NotDone
Plant locked against switching on.
Done
The plant is unlocked after complete parameterization (Configura-
tion 2 and Configuration I/Os also have a value "done"), i.e. it can
be switched on.
Reset Required !!
Passive
Execute
Reset required after successful parameterization in Configuration
1. Assumes the appropriate presettings for Configuration 2.
After reset, value automatically goes from execute to passive.
