6.7. Cool Cell
The controller can control one cool cell
output. This cooling system reduces the air
temperature by evaporation of water into the
air stream.

Principle of operation:
The cool cell output
can either operate according to the inside
temperature or outside temperature: it starts
running in timer mode when the inside (or
outside) temperature rises and reaches the
output’s start temperature; the output stops
when temperature falls below a user-defined
value. It can also stop when humidity levels
are too high (see RH Compensation in chap-
ter 10).
Start/Stop Temperatures:
If the cool cell
output operates according to the inside tem-
perature, its start and stop temperatures are
related to the set point; this means they are
automatically adjusted when the set point
changes. That is not the case if cool cells op-
erate according to the outside temperature.
Operating Time Range:
The user can specify
a time range during which the cool cell output
can run. This allows deactivating the output
at night for instance.
Cool Cell LED:
The cool cell LED located on
the faceplate of the controller tells the status
of cooling cycles:
LED is Off: the cool cell output is off
LED is On:
the cool cell output is on

2. Set the following parameters:
Temperature —
Select
“inside”
if the opera-
tion of cool cells is based on the inside tem-
perature; select
“outside”
if it is based on the
outside temperature.
On temperature —
Select the temperature
(inside or outside T°) at which the cool cell
output starts.
Off temperature —
Select the temperature
(inside or outside T°) below which the cool
cell output stops.
On & Off times —
Set the
“On & Off Times”
of
the cool cell timer.
Start & stop at —
Specify the period of time
over which the output can run.
6.8. Misting Output
The controller can control one misting output.
When the room temperature reaches the start
temperature of the output, mist units are
activated and run in timer mode according to
their minimum timer (Min On Time & Min Off
Time). Then, as temperature rises, a gradual
transition is made from the minimum timer
towards the maximum timer (Max On Time &
Max Off Time). The second mist timer is fully
used when the room temperature reaches the
Maximum Temperature parameter setting.
The misting output is disabled when the
temperature falls below a user-defined value.
It can also stop when humidity levels are too
high (see RH Compensation in chapter 10).

Start / stop temperatures:
Operating tem-
peratures of the mist output can either be
related to the set point – which means the
controller automatically adjusts them when
the set point changes – or they can be set
as absolute values. Refer to the Installation
Setup chapter to choose if the output follows
the set point or not (sec. 4.5).
Operating time range:
You can specify a
period of time over which the mist output is
allowed to run. This allows deactivating the
mist output at night for instance.
Mist LED:
The Mist LED located on the
faceplate of the controller tells the status of
misting cycles:
LED is Off: The mist output is off
LED is On: The mist output is on
