8061 TT Support Module

Application

The Aprilaire 8061 is designed to offer versatility in climate

control. A set of onboard dipswitches allows you to select whether you want as many as two sensor inputs per support module to control, monitor or even do a combination of both. This temperature data is sent by digital communications back to an Aprilaire 8870 Communicating Thermostat, allowing you to accurately control and monitor temperature in a given area or multiple areas. The Aprilaire 8870 Communicating Thermostat can support up to four Support Modules (Tf or TrH).

Single Support Module Installation

Install the Aprilaire thermostat according to the instruction manual supplied with it. Check to ensure that thermostat is operating (display shows correct temperature). CAUTION: Remove the thermostat from the subbase before wiring the support module to avoid damage from live wire.

Choose the wall location where the 1T module will be mounted. Locate in an area free from drafts. Do not mount support module on an exterior wall. Run CAT -5 wire from the thermostat to the support module location. A void routing wires near sources of electronic noise such as computer monitors, fan motors or fluorescent lights.

Maximum distance from the thermostat is 1000 ft. (300m).

OpeD the support module case by pulling the cover straight forward.

4. Remove the circuit board from the base by pulling back the

latch that holds it at the bottom center.

Use the subbase as a template to mark the mounting hole

locations on the wall. The word "TOP" will be written in the subbase. Position the subbase so that the wires can be pulled through the hole in the top left-hand comer. Drill size for the wall anchors is 3/16 inch. Mount the subbase using the two #6 screws and anchors provided (larger screws will prevent the circuit board from properly snapping into place).

If side access is preferred for wiring, clip out the side vents

at the locations shown below.

6. Snap the circuit board back into the subbase by sliding the top of the board in first and then snapping down on the bottom. Check to be sure that the latch holds the board

properly.

7. Strip y. inch of insulation from the four wires at the support module. Install the wires in the terminals labeled RSR, RSC, RSB and RSA. One twisted pair of wires should be used for the RSR and RSC connection and another pair of

twisted wires should be used for the RSB and RSA connection. Push the extra wire back into the wall cavity. Seal the hole in the wall around the cable to eliminate any draft that might affect the sensor.

8. Connect the wires on the thermostat subbase to the terminals labeled RSR, RSC, RSB and RSA. Make sure

that each terminal on the support module is wired to the terminal with the same label at the thermostat.

9. If necessary, change the Tf support module dipswitch

settings. Note: switches must be set prior to powering the support module (support module is powered when thermostat is returned to its base). If switches need to be

changed after powering the support module, the thermostat must be removed from its base for a minimum of 15 seconds to ensure proper reset of the support module.

10. Mount the themostat on the subbase and confirm that it is displaying the correct temperature.

Multiple Support Module Installation

up to 4 support modules can be connected to provide temperature averaging in a large area or for several zones being

controlled by the same system. The maximum cumulative distance between the support modules and the thermostat is

1000 ft.

CAUTION: Make sure that there is no power to the support modules by removing the thermostat from the subbase.

Wire the first support module using the single support module instructions. Daisy chain the remaining support modules as shown below.

Dipswitch 3 - Temperature Sensor 1

Each support module has two sensors, Sensor I and Sensor 2. Determine whether you want the Sensor I input to monitor or control temperature. If dipswitch number 3 is in the "off' position, it will monitor the temperature. If the support module is set to Address 1 and the Sensor 1 input is set to "monitor", then the monitored temperature will be displayed as the remote temperature in the lower left hand corner of the thermostat. Otherwise, the monitored value will only be available through the software that supports this specific function.

If dipswitch 3 is set to the "on" position, it will use the reported temperature to control the thermostat. The sensor control temperature will be displayed on the thermostat. If multiple

support modules are daisy chained together, all of the sensors set to control will be averaged and the average temperature will be displayed on the thermostat.

Dinswitch 4 - Temperature Sensor 2 Determine whether you want the Sensor 2 input to monitor or

control temperature. If dipswitch number 4 is in the "off" position, it will monitor the temperature.

If dipswitch 4 is set to the "on" position, it will use the reported temperature to control the thermostat. The sensor control

temperature will be displayed on the thermostat. If multiple support modules are daisy chained together, all of the sensors set to control will be averaged and the average temperature will be displayed on the thermostat.

Dioswitch 6 - TIff2 or Onboard Sensor Determine whether you want the Sensor 1 input to use the

temperature sensed by the onboard thermistor or to use the input from a remote sensor (i.e. flush mount sensor or duct/outdoor

sensor). If dipswitch number 6 is in the "off' position it will use the remote sensor inputs wired to the TIm terminals. If the dipswitch is in the "on" position, it will use the temperature

input from the onboard thermistor. This option only exists for the Sensor 1 input and can still be configured to monitor or control. The thermostat will not display temperature (Sensor 1 or Sensor 2) values if dipswitch 6 is set to TIff2 without wiring a sensor to the TIm terminal.
