User’s Guide
Read this guide carefully before using the controller.
PRECAUTIONS
We strongly recommend connecting the controller to an alarm system, and installing
a supplementary natural ventilation system as well as a back-up thermostat on at
least one cooling stage. Refer to the wiring diagram enclosed with this user’s guide
to connect the thermostat.
Input and output circuitry is protected against overload or overvoltage. However, we
recommend installing an additional protection device on the supply circuit as well as
an external relay on all ON-OFF stages to prolong the life of the controller.
To avoid exposing the controller to harmful gases or excessive humidity, it is
preferable to install it in a corridor.
The room temperature where the controller is located MUST ALWAYS REMAIN
BETWEEN 32° AND 104°F (0° AND 40°C).
DO NOT SPRAY WATER ON THE CONTROLLER.
FOR CUSTOMER USE
Enter below the serial number located
on the side of the controller and retain
this information for future reference.

GLOSSARY
or Located to the left of a parameter name, these arrows indicate that the user must either scroll up
or down to access the parameter, by pressing push-button A (scroll up) or B (scroll down) found
in the rightmost section of the faceplate.
A or B
Located to the left of a parameter name, the circled letters A or B indicate that the user accesses
the parameter directly, by pressing push-button A or B found in the rightmost section of the
faceplate.
Bandwidth
The bandwidth is the temperature interval within which the variable speed fans of a given stage
increase or decrease in speed proportionally to the temperature.
Cascading heaters
Heaters operate in a sequence. As the average room temperature drops, additional heaters are
turned on as needed.
Default value
A typical parameter setting defined at the factory.
Differential
The differential is the temperature difference between the moment the constant-speed fans or
heating units of a given stage start running and the moment they return to a stop.
Hysteresis
A hysteresis is used to smooth the transition from one state to another. For example, when the
temperature drops to the cut-off point for a stage of constant-speed fans, the fans will actually
cut off at slightly less than the cut-off point. This way, if the temperature fluctuates around the
cut-off point without dropping significantly below it, the controller will not oscillate between two
states. For example, if the hysteresis is 0.3°F and the stage 2 fans are programmed to cut off at
75.0°F, the cut-off will actually occur at 74.7°F.

Messages
Messages appear in the LED display alternating with the value of the corresponding setting.
Some parameter adjustments are displayed both as a relative value and an absolute
temperature. This applies to all heating and cooling differentials, the mist differential and to the
heater and alarm offsets. The parameter is first displayed as a relative value. The
corresponding absolute temperature is displayed after 10 seconds if no action is taken by the
user. The absolute value is the temperature at which the stage turns on (except in the case of
the heater and mist offsets, where the value displayed is the temperature at which the stage
turns off). If the user turns the adjustment knob, the relative value reappears.
Here is an example of the sequence followed by the display when the user turns the selection
knob to the “STAGE 3 DIFF.” position.
1. The current differential for stage 3 flashes on the display, alternating with “St 3”.
2. If, after approximately 10 seconds, no action is taken by the user, the absolute
temperature value is displayed, alternating with “St 3”. In this case, the absolute value
is: Set Point + Stage 1 Bandwidth + Stage 2 Offset + Stage 2 Bandwidth + Stage 3
Differential.
3. When the user turns the adjustment knob to adjust the Stage 3 Differential, the relative
value reappears on the display.
In the case of the mist and heating units, when the user adjusts the offset, the stopping
temperature is displayed with the letters “StOP”.
Minimum ventilation cycle
When the room temperature is below the set point, the stage 1 fans operate intermittently to
provide minimum ventilation to the room.
Minimum ventilation speed curve
The user can define a minimum ventilation speed curve to adjust the stage 1 minimum speed
automatically over a given time period. The minimum speed increases over time as the animals
grow.
Offset
An offset is a temperature difference from the set point that normally defines a cut-off point for a
stage operation. For example, a heater offset of 2.0°F means the heaters will turn off at 2.0°F
above the set point.
RAYDOT Ventilation Control
Page 3
RVS-22HA User’s Guide
Set point
The set point is the target room temperature. When the temperature is above the set point, the
controller cools the room by turning on the cooling fans. When the temperature is below the set
point, the controller heats the room by turning on the heaters.
Temperature curve
The controller can be set to automatically change the temperature set point over a given period
of time in accordance with the user’s requirements. The set point decreases over time as the
animals grow.
Zoned heaters
When zoned heaters are used, heaters in each zone operate according to their corresponding
probes rather than from the average temperature of the entire room. This way, heaters operate
independently from one zone to the other. See page 25 “DIP SWITCHES AND PROBES” for
more information on zone temperatures.

All outputs (except for alarms if “ind” is chosen at parameter Alarm Individual/All) are controlled
by the “room temperature”, which is the temperature averaged from # 1 to 4 probe readings.
Heaters follow either the room temperature or a zone temperature, depending on user setup. A
humidity probe may be used to lower the humidity level by activating stage 1 or by deactivating
the mist stage.
It is important to read both the RVS-22HA Installation Guide and the present User’s Guide. The
Installation Guide provides information on physical characteristics of the controller, mounting,
connections, probes, troubleshooting and technical specifications. The User’s Guide explains
the workings of the controller parameters.

PARAMETER DESCRIPTION
LOCKED PARAMETERS
By setting DIP switch # 1 to the ON position, all parameters, except the Main Set Point and
Stage 1 Minimum Speed, are “locked” to prevent modifications. After the user has set
parameters to the desired values, he may want to lock these values for safety.
ROOM TEMPERATURE MINIMUM/MAXIMUM
The actual room temperature, averaged from
activated interior probe readings, controls all
outputs (except the heaters if zoned) and
alarms (except if “ind” is chosen at parameter
Alarm Individual/All).

High values, along with all individual probe lows and highs, by moving the SET knob back
and forth until “CLr” appears on the display. This reading is displayed to the nearest 0.1°,
from -6.0°F to 168.6°F (-21.1°C to 75.9°C).
Room Temperature High (Message: “Hi”)
Continually updated, this reading shows the highest room temperature reached since the last
clear. While this setting is selected, the user may clear the Room Temperature High and
Low values, along with all individual probe lows and highs, by moving the SET knob back
and forth until “CLr” appears on the display. This reading is displayed to the nearest 0.1°,
from -6.0°F to 168.6°F (-21.1°C to 75.9°C).
Probe 1 (to 4) Readout (Messages: “Pr[1-4]”)
These settings display the actual temperature read by the displayed probe if that probe is
activated (see the DIP switch table). These temperatures are used to calculate the Room
Temperature Readout as well as the A and B temperature zones, used for the heaters.
These readings are displayed to the nearest 0.1°, from -6.0°F to 168.6°F (-21.1°C to 75.9°C).
Probe 1 (to 4) Low (Messages: “Pr[1-4]Lo”)
These readings, continually updated, display the lowest temperature read by the displayed
probe since the last clear. Displayed probes must be activated to access these readings.
While this setting is selected, the user may clear the Probe [#] Low reading, along with all
individual probe lows and highs, and along with the Room Temperature Low and High, by

moving the SET knob back and forth until “CLr” appears on the display. These readings are
displayed to the nearest 0.1°, from -6.0°F to 168.6°F (-21.1°C to 75.9°C).
Probe 1 (to 4) High (Messages: “Pr[1-4]Hi”)
These readings, continually updated, display the highest temperature read by the displayed
probe since the last clear. Displayed probes must be activated to access these readings.
While this setting is selected, the user may clear the Probe [#] High reading, along with all
individual probe lows and highs, and along with the Room Temperature Low and High, by
moving the SET knob back and forth until “CLr” appears on the display. These readings are
displayed to the nearest 0.1°, from -6.0°F to 168.6°F (-21.1°C to 75.9°C).
Test Mode (Message: “tESt”)
The Test Mode allows the user to simulate a temperature reading in order to test the
reaction of the control at a given temperature.
When the Test Mode is OFF, the control operates according to Room Temperature
Readout.
To activate the Test Mode, the user must turn the SET knob back and forth until “tESt”
appears on the display. This unlocks the Test Mode, which uses the Room Temperature
Readout as its default simulated value. The user may then modify this value to test the
control reaction to a given temperature.
To deactivate the Test Mode, the user must move the SET knob back and forth; “tESt” will
appear alternating with “OFF” on the display. If the user does not turn a knob or a push a
button for five minutes, the control will deactivate the Test Mode automatically.
This parameter is adjusted in 0.1° increments from OFF, -6.0°F to 168.6°F (-21.1°C to
75.9°C).

A Adjust Day (Display: “d#: [value]”, where # = 1 to 9, or “10: [value]”)
The user can program up to 10 points on the ramping curve. Each point, which represents a
day number, may be set to any value between 1 and 255.
To obtain a ramping curve having less than 10 points, first program the day numbers you
require. Then program an additional day with a day number inferior to that of the last day
number you require. The controller will react by leveling the temperature to the value
programmed for the last day number you require on the ramping curve. See the four-point
temperature curve below.
B Adjust Temperature (Display: “t#: [value]”, where # = 1 to 9, or “10: [value]”)
The user can program up to 10 temperatures that correspond to the day numbers
programmed on the ramping curve. Temperatures are adjusted in 0.1° increments, from
-40.0°F to 100.0°F (-40.0°C to 40.0°C).

Minimum Ventilation On Time (Message: “On”)
This parameter adjusts the time during which the minimum ventilation timer is on. When the
Room Temperature Readout is below the Set Point, stage 1 is activated at Stage 1
Minimum Speed during the time specified for this parameter, and is deactivated for
Minimum Ventilation Off Time. To deactivate minimum ventilation, simply set this
parameter to 0. Minimum Ventilation On Time is adjusted in 15-second increments, from 0

Minimum Ventilation Off Time (Message: “OFF”)
When the Room Temperature Readout is below the Set Point, the control is in minimum
ventilation. During minimum ventilation, stage 1 is activated at Stage 1 Minimum Speed
during Minimum Ventilation On Time and deactivated during the time specified for this
parameter. To have stage 1 operate continuously at Stage 1 Minimum Speed when in
minimum ventilation, simply adjust this parameter to 0. Minimum Ventilation Off Time is
adjusted in 15-second increments, from 0 to 900 seconds.

Humidity reaches Humidity Set Point, stage 1 operates at Stage 1 Minimum Speed
regardless of the minimum ventilation timer. Stage 1 accelerates as Humidity increases, to
reach Stage 1 Minimum Speed + Relative Humidity Speed Compensation when
Humidity reaches Humidity Set Point + 10 RH%. If stage 1 is already activated, its
minimum speed will be adjusted in the same manner. Stage 1 modulates from the
compensated minimum speed to 100% according to the Room Temperature Readout. This
parameter is adjusted in 1 RH% increments, from 10 RH% to 90 RH%. The previous
parameter description provides an example.

Relative Humidity Speed Compensation (Message: “SPd”)
This parameter, visible if the Compensation Option parameter is set to ON, is used to
adjust stage 1’s speed compensation for dehumidification. Stage 1’s speed will increase by
this amount when Humidity reaches Humidity Set Point + 10 RH%. Setting this parameter
to 0% does not affect stage 1’s speed when it is already activated by temperature demand,
but activates stage 1 continuously at Stage 1 Minimum Speed when the Room
