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.

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.
RVS-22HA User’s Guide 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.
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.
RVS-22HA User’s Guide VENTILATION SYSTEM OVERVIEW The RVS-22HA is a powerful environmental controller that can manage two variable ventilation stages and two on/off ventilation stages. Depending on user setup, the on/off stages can either be heating, mist or ventilation stages.

RVS-22HA User’s Guide 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.
RVS-22HA User’s Guide 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.
RVS-22HA User’s Guide 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.

MIN The stage 1 bandwidth is the temperature range within which stage 1 accelerates from Stage 1 Minimum Speed to its maximum speed (100%). When the Room Temperature Readout reaches the Set Point, stage 1 operates continuously at minimum speed.
RVS-22HA User’s Guide Minimum Ventilation Cycle Minimum Ventilation On Time Stage 1 minimum speed OFF Minimum Ventilation Off Time Motor Type (Message: “tyP”) This parameter allows the user to choose the motor type for stage 1. The right motor type ensures correct supply voltage at a given speed. Refer to the motor type table for the list of available motor types. HUMIDITY MINIMUM/MAXIMUM (STAGE 1) Readout (Message: “rH”) ROOM TEMP. MIN This parameter displays the actual relative humidity.
RVS-22HA User’s Guide RELATIVE HUMIDITY COMPENSATION (STAGE 1) Compensation Option (Message: “OPt”) ROOM TEMP. MIN This parameter activates or deactivates all humidity logic. Setting this parameter to OFF eliminates the Relative Humidity Speed Compensation logic as well as the Humidity Turn Off mist logic. This parameter can be set to OFF or ON.

RVS-22HA User’s Guide 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%.
RVS-22HA User’s Guide De-Icing Cycle Time (Message: “Cyc”) This parameter, visible if DIP switch # 11 (de-icing option) is set to ON, establishes the length of time during which stage 2 de-icing is inactive. If stage 2 stays deactivated for a longer period of time than De-Icing Cycle Time, stage 2 is activated at minimum speed for De-Icing On Time. This parameter is adjusted in 1-minute increments, from 1 to 720 minutes.
RVS-22HA User’s Guide DIFFERENTIAL (STAGE 3) Stage 3 Differential (Message: “St 3”; absolute message: “St 3”) This parameter is invisible if DIP switches # 6 and 9, or # 6 and 7, are set to ON. This setting adjusts the temperature at which stage 3 is activated. ROOM TEMP. MIN ALARM OFFSETS HEAT 1 HEAT 2 MIST SET POINT / T°CURVE OFFSET / DIFF. CURRENT RAMPING DAY OFFSET / DIFF. MIN.

RVS-22HA User’s Guide TIMER (MIST) Mist On Time (Message: “On”) ROOM TEMP. MIN This parameter, accessible if DIP switch # 9 is set to ON (mist stage enabled), adjusts the mist timer ON time. Refer to the DIP switch table in the last pages of this document. This parameter adjusts the mist timer ON time. When the temperature is above Set Point + Mist Offset + Mist Differential, the mist is activated on a timer. The mist is activated during this period of time and then deactivated for Mist Off Time.
RVS-22HA User’s Guide OFFSET/DIFFERENTIAL (MIST) Offset (Message: “OFt”; absolute message: “StOP”) ROOM TEMP.

RVS-22HA User’s Guide rises to Set Point – Heater 1 Offset – Heater 1 Differential, with DIP switch # 8 in the OFF position. In the latter case, this parameter will display “-----“ indicating that this value is not used to calculate the activation and deactivation points. This parameter is adjusted in 0.1° increments, from -10.0°F to 20.0°F (-5.5°C to 11.0°C).
RVS-22HA User’s Guide Differential. This parameter is adjusted in 0.1° increments, from 0.5°F to 20.0°F (0.3°C to 11.0°C).
RVS-22HA User’s Guide The alarm is normally activated, but will be deactivated 13 seconds or more after one of the following events: 1. The RVS-22HA loses its power; 2. The temperature* is lower than Low Alarm Offset; 3. The temperature* is higher than High Alarm Offset; 4. The temperature* is higher than the Critical High Alarm parameter; 5. An active temperature probe is defective (disconnected, open circuit, short-circuit).
RVS-22HA User’s Guide Inlet 1 Step 0 (Message: “1 S0”) This setting, visible if Inlet 1 is set to ON, defines the position inlet 1 will take when temperature is below the Set Point. Inlet will never be opened less than this value unless it is completely deactivated using the Inlet 1 option. As temperature nears the Set Point (Set Point – 0.4°F or Set Point – 0.2°C), inlet’s opening will start to increase as temperature rises to reach Inlet 1 Step 1 Lo when temperature is exactly at the Set Point.
RVS-22HA User’s Guide Inlet 1 Over Bandwidth (Message: “1 Obd”) This parameter, visible if Inlet 1 is set to ON, sets the temperature at which inlet 1 opening will be equal to Inlet 1 Over Open. When temperature is higher than the last ventilation stage’s activation point, inlet 1 has two possible behaviors depending on the Inlet 1 Drop option.
RVS-22HA User’s Guide reach Inlet 2 Step 2 Lo when stage 2 is activated at minimum speed. This parameter is adjusted in 1% increments, from 0% to 100%. Inlet 2 Step 2 Lo (Message: “2 S2L”) This setting, visible if Inlet 1 and Inlet 2 are set to ON, defines the position inlet 2 will take when stage 2 is activated at its minimum speed. Inlet opening will increase as stage 2’s speed increases to reach Inlet 2 Step 2 Hi when stage 2 is running at full speed.
RVS-22HA User’s Guide fixed differential of 0.5° will be used on this logic. If this option is set to OFF, inlet 2 will increase its opening progressively throughout this Inlet 2 Over Bandwidth to reach Inlet 2 Over Open at the end of this same bandwidth. Example: Inlet opening with drop option set to OFF Ventilation Over Open Step 3 Stage 3 Step 2 Hi Step 2 Lo Stage 2 Step 1 Hi Step 1 Lo Stage 1 ABS Minimum opening } Minimum Ventilation Step 0 0.4°F 0.
