Installation

Location Considerations

Locate the T606MSx-4 or T606MSx-4+PIR Series Temperature and Humidity Controller:
on a partitioning wall, approximately 5 ft ( 1. 5 m) above the floor in a location of average temperature
away from direct sunlight, radiant heat, outside walls, outside doors, air discharge grills, or stairwells; or from behind doors
away from steam or water pipes, warm air stacks, unconditioned areas (not heated or cooled), or sources of electrical interference
For integrated Passive Infrared (PIR) models, be sure that the controller is located centrally, where occupant movement is abundant.
Note: Allow for vertical air circulation to the controller. To install the controller:
1. Use a Phillips-head screwdriver to remove the security screw if it is installed on the bottom of the controller cover.
Note: Normally, the security screw is packaged separately in a plastic bag with the controller. Skip this step if the screw is not installed on the bottom of the cover.
2. Pull the bottom edge of the controller cover and open the controller as illustrated in Figure 1.

between the cover and the Printed Circuit Board (PCB). This connection allows for proper wiring of the occupancy sensor. Carefully remove the wiring connection from the PCB by pulling up on the connector block. Do not attempt to remove the connector block by pulling on the wires.
3. Carefully pull the locking tabs on the right side of the controller mounting base and unlock the PCB. Open the PCB to the left as illustrated in Figure 2.
Note: If you need to install the thermostat on an electrical junction box, use 2-1/2 x 4 in. (63 x 101 mm) square boxes with mud ring covers, and avoid smaller 1-1/2 x 4 in. (38 x 101 mm) square or 3 x 2 in. (76 x 51 mm) boxes. This procedure ensures you have enough space for cabling a nd end- of-line devices, if needed.
Note: For surface-mount applications, use durable mounting hardware such as Molly bolt anchors that cannot be easily pulled out of the mounting surface.
7. Secure the base to the wall surface using two mounting screws as illustrated in Figure 3.
Note: Be careful not to overtighten the mounting screws.
PCB Locking
4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the hole in the controller mounting base.
5. Align the controller mounting base on the wall and use the base as a template to mark the two mounting hole locations.
6. Position the controller mounting base so that the arrow on the base points upward to indicate the top of the controller.
8. Swing the PCB back to the right and carefully snap it into the locking tabs on the controller mounting base.
9. Remove the screw terminal blocks that are attached to a disposable adhesive. Figure 4 illustrates the locations of the screw terminal blocks on the controller.

When an existing controller is replaced, remove and label the wires to identify the terminal functions. When a T606MSx-4 or T606MSx-4+PIR Series Controller is replaced, simply remove the old screw terminal blocks and reinsert them onto the PCB of the replacement controller.
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical connections to avoid electric shock.
CAUTION: Risk of Property Damage.
Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment.
IMPORTANT: Make all wiring connections in accordance with local, national, and regional regulations. Do not exceed the electrical ratings of the T606MSx-4 or T606MSx-4+PIR Series Temperature and Humidity Controller.
To wire the controller:
1. Strip the ends of each wire 1/4 in. (6 mm) and connect them to the appropriate screw terminals as indicated in Figure 5.
2. Carefully push any excess wire back into the wall. Note: Seal the hole in the wall with fireproof
material to prevent drafts from affecting the ambient temperature readings.
3. Reinsert the screw terminal blocks onto the PCB. If multiple wires are inserted into the terminals, be sure to properly twist the wires together prior to inserting them into the terminal connectors.
4. For PIR models, carefully reattach the PIR connector to the PCB.
5. Reattach the controller cover to the mounting base (top side first).
6. Use a Phillips-head screwdriver to install the security screw on the bottom of the controller cover if desired. The security screw comes packaged separately in a plastic bag with the controller.

Humidification operates only when the controller is in heating mode (system mode = Heat, or system mode = Auto and mode at the controller is Heat). If a call for humidification occurs and the fan is off, the fan is first turned on, then the humidifier output is activated.
In addition to reaching the humidity setpoint, the following events can stop humidification operation:
RH sensor is out of range
System mode switches to Off or Cool
System mode is Auto, but the controller mode changes from Heat to Cool

Humidity Setpoint Reset

The humidity setpoint reset function minimizes condensation found on windows and building structures during the colder months. An outdoor air sensor connected at the controller is required for humidity setpoint reset function.
When the outdoor air temperature falls below the selected high temperature setpoint (RH HT), the humidity setpoint decreases. The lowest humidity setpoint is reached at the selected low temperature setpoint (RH LT).

High Limit Humidity Sensor Operation

The T606MSx-4(+PIR) Series Temperature and Humidity Controller includes a high limit sequence. This sequence allows the use of a remote 0 to 10 VDC humidity sensor to keep the humidifier from saturating the supply air. The remote sensor throttles the output of the Proportional plus Integral plus Derivative (PID) loop if the high limit sensor measures humidity in the duct over the high limit value (85%) less the proportional band of the high limit PID loop. If no sensor is detected at the high limit (HL) connector, this sequence is disabled at the controller.
The Reset Humidity Setpoint (RE Sp) determines the difference between the original se tpoin t and the lowe st setpoint. For example, in Figure 8, the reset humidity setpoint is set to 20%; therefore, the humidity setpoint decreased from 45% to 20%.

Dehumidification Operation

Dehumidification operation depends upon the dehumidification lockout setting.
If Dehumidification Lockout (Dhu LCK) is set to On:
Dehumidification operates when the controller is in cooling mode (system mode = Cool, or system mode = Auto and the mode at the controller is Cool). If a dehumidification demand exists and the fan is off, the fan is first turned on, then the dehumidification output is activated.
In addition to reaching the dehumidification setpoint, the following events can stop dehumidification operation:
RH sensor is out of range
System mode is switched to Off or Heat
System mode is Auto but controller mode is Heat
Room temperature falls below the cooling setpoint less the deadband value
Outside air temperature falls below the dehumidification outside air temperature lockout value

FIG:rm_tmp
Dehumidification operates when the controller is in any mode except Off. If a dehumidification demand exists and the fan is off, the fan is first turned on, then the dehumidification output is activated.
In addition to reaching the dehumidification setpoint, the following events can stop dehumidification operation at any time:
RH sensor is out of range
The controller automatically switches the occupancy level between Occupied and Unoccupied as req uired , when local movement is sensed. In the Occupied mode, if no movement is detected beyond the Unocc TM parameter setting, the mode changes to Unoccupied. Once movement is detected, the mode changes back to Occupied.
Occupancy sensing is enabled only if a PIR cover is installed. The PIR cover, when installed, is auto detected.
System mode is switched to Off
Outside air temperature falls below the dehumidification outside air temperature lockout value
No active temperature lockout protection is available while the system is in dehumidification mode. If dehumidification operation causes the room temperature to fluctuate, the controller reacts by either activating the cooling or heating outputs based on the current system mode setting.

Occupancy Sensor Operation – T606MSx-4+PIR Series Controllers

A T606MSx-4+PIR Series Controller (or a T606MSx-4 Series Controller equipped with a PIR accessory cover) provides advanced occupancy logic.
Note: The PIR strategy is an occupied strategy. If the controller is programmed to be Unoccupied, the PIR function does not have an effect on the occupancy strategy.

PIR Diagnostic LEDs

The diagnostic LEDs inside the PIR lens brighten when movement is detected within the first 30 minutes after powerup. The LEDs do not light up or brighten after the initial 30-minute period.

Setpoints

The installer must be certain that the difference between the Occupied and Unoccupied setpoints can be recovered within a timely fashion to ensure occupancy comfort. In addition, the difference between the two setpoints must be large enough to warrant maximum energy savings.
These setpoints and Unoccupied timers are adjust able to allow for customization, as dictated by the individual space requirements. See Figure 10 for an example of increasing room temperature setpoints.
