4.6. RH Compensation
Setup
The controller offers different ways to com-
pensate for high and low relative humidity
(RH) levels in the barn. This section shows
how to enable the desired RH compensation
functions.
1. Select:

User
RH Compens**
* A password may be required to access this menu.
** This menu is accessible if a humidity sensor is
enabled (sec. 4.7.1).
RH Compensation
RH Compens Heaters?
Yes
Use Mist Shutoff?
Yes
Use Mist on Lo %RH
Yes
Use Cool Cell Shutoff
Yes
2. Enable or disable the following relative
humidity (RH) compensation options:
The following parameters are common
to all programs of the controller.
RH compensation with heaters —
The con-
troller can compensate for high humidity
levels by activating heating outputs in timer
mode. Select
“Yes”
to use this compensation
method.
Mist Shutoff —
The controller can deactivate
the misting output when humidity levels are
too high. Select
“Yes”
to use this compensa-
tion method.
Misting on low humidity levels (% RH) —
The
controller can activate misting outputs when
humidity levels are too low. Select
“Yes”
to
use this compensation method.
Cool cell shutoff —
The controller can de-
activate the cool cell output when humidity
levels are too high. Select
“Yes”
to use this
compensation method.
4.7. Probe Setup
4.7.1. Probe Activation
Follow these steps to enable or disable the
probe inputs.

# Outside T° Probe
2
Use SP Probe?
Yes
2. Enable or disable the following probe
inputs:
The following parameters are common
to all programs of the controller.
Inside probe —
Select the number of inside
temperature probes that are connected to the
controller (1 to 8 probes).
Inside relative humidity (RH) probe —
Select
“Yes”
if an indoor humidity probe is connected
to the controller.
Outside relative humidity (RH) probe —
Select
“Yes”
if an outdoor humidity probe is con-
nected to the controller.
Water meter —
Enable the desired number
of water meter inputs (1 to 9). Note that the
controller only has 1 built-in water meter in-
put. Connect water meters 2-9 to an external
water meter module.
Outside T° —
Select the number of outside
temperature probes that are connected to the
controller (0 to 2 probes).
Static pressure (SP) probe —
Select
“Yes”
if
a static pressure sensor is connected to the
controller.
4.7.2. Probe & Water Meter Cali-
bration
You can slightly adjust the reading of each
probe input in order to obtain accurate and
uniform readings from all probes. In addition,
if a water meter is used, you must calibrate
its water flow rate.

2. Adjust the reading of the probes (if
required).
The following parameters are common
to all programs of the controller.
Temperature probes (indoor & outdoor) —
The reading of inside and outside temperature
probes can be adjusted of ±5°F (±2.8°C).
Relative humidity probe —
The reading of
inside and outside humidity probes can be
adjusted of ±3%.
Static pressure probe —
The reading of
the static pressure probe can be adjusted
of±0.030”WC (±8Pa).
Water meter calibration —
Specify the flow
rate of each water meter. It can be adjusted
from 1 to 100 gallons (or liters) per pulse.
