THESE INSTALLATION INSTRUCTIONS ARE FOR THE HUMIDISTAT ONLY!
For DriSteem humidifier installation, follow DriSteem humidifier installation instructions.
WARNING
This product must be installed by a qualified heating and air
conditioning contractor. Failure to do so can result in serious
injury from electrical shock or damage to product, and can
void product warranty due to possible product misapplication.
WARNING
1. Contact with energized electrical circuits can cause
serious injury from electrical shock. Disconnect electrical
power to the humidifier before starting installation.
CAUTION
1. Do not set humidity higher than recommended or moisture
can accumulate, which can cause bacteria and mold
growth or dripping water into building spaces. Dripping
water can cause property damage; bacteria and mold
growth can cause illness.
2. Do not set humidity up to recommended levels if there is
condensation on the inside of windows. Condensation
damage
can result.

failure endangers human life and/or
property, it is the responsibility of the
owner, designer and installer to add
additional safety devices to prevent or
detect a system failure caused by such
a device failure. The manufacturer of
this device cannot be held liable for
any damage caused by such a failure.
WARNING!
Live electrical components
During installation, testing, servicing
and troubleshooting of DriSteem
products, it may be necessary to work
with live electrical components. Have
a qualified licensed electrician or other
individual who has been properly
trained in handling live electrical
components perform these tasks.
Failure to follow all electrical safety
precautions when exposed to live
electrical components could result in
death or serious injury.

DRISTEEM TCI AND TRI2 HUMIDISTAT INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

INSTALLATION
• Install the controller on an easily accessible interior
wall, approximately 1.5 m above the floor in an area
of average temperature.
• Avoid direct sunlight or other heat sources (e.g. above
radiators and heat emitting equipment).
• Avoid locations behind doors, outside walls,and below
or above air discharge grills and diffusers.
• Location of mounting is less critical if external sensors
are used.
• Ensure adequate air circulation to dissipate heat
generated during operation.
• Observe local regulations.
• Do not mount in a wet or condensation prone
environment.
INSTALLATION INSTRUCTIONS
1. Connect the wires to be connected to the terminals of
the power case according to wiring diagram.
2. Install the mounting plate to the flush mounting box.
Notes:
• Make sure the nipple with the front holding screw is
facing to the ground (TCI models only).
• Make sure the mounting screw heads do not stand out
more than 0.2" (5 mm) off the surface of the mounting
plate.
3. Ensure the jumpers are set correctly (TCI models only).
4. Slide the two latches located on the top of the front
part into the hooks at the upper side of the mounting
plate.
5. Carefully lower the front part until the interconnector
reaches the mounting-plate. Continue pressing in a
gentle way until the front part is fully connected. While
inserting the connectors, a slight resistance can be felt.
This is normal. Do not use excessive force.
6. With a Phillips-type screw driver of size #2, carefully
tighten the front holding screw to secure the front part
to the mounting plate. This screw is located on the
front lower side of the unit. There is no need to tighten
the screw too much (TCI models only).
JUMPER CONFIGURATION (TCI MODELS ONLY)
Jumpers are mounted vertically only.
1. A0 - Selection of output signal type
• Left position: voltage output (0 - 10 V) factory
default.
• Right position: current output (0 - 20 mA)
2. UI - Selection of input signal type

LED INDICATORS
The BACnet interface features a green LED and a red LED for indication of

received, and the red LED is lit when an outgoing packet is transmitted to the
bus. At power-up, both LED blink twice simultaneously as a sign of the boot
process being completed. A constantly lit LED serves as an indication of a fault
condition in the reception or sending process.

1 “Auto-detect baud rate”-mode
When this option is selected, the AEC-BAC will detect the baud rate of the RS485 network. The AEX-BAC will stay in baud rate detection mode until
it successfully decodes a package sent from device with address = 0 with a baud rate which is supported by the AEX-BAC. The baud rate detection
mode will be entered once at hardware start-up and after a prolonged communication failure.
2 “Auto increment”-function
When this function is enabled and an automatic AEC-PM1 parameter load is executed at power up of the controller, the following variables will be
incremented and written back to the AEC-PM1 unit:
- CO03 Communication address. This is incremented only if the value is not already 127 with respect to CO05 – the address of the highest master. If
CO05 is equal or less than the newly incremented value of CO03, then CO05 is written to be 127 (the maximum value of CO05 possible).
- CO06 … CO09 Device object ID. This is incremented only if the value is not already “4194304”.
3 “Auto-build of device object name”-function
The BACnet standard requires that the each BACnet endpoint has a unique name on the network (device object name). The initial name of the AEX-
BAC module is “AEX-BAC” equal for all devices. This means that device object names need to be edited manually.
Using the auto-build-function the device object name can be automatically assembled using the label AEX-BAC followed by the contents of CO06 –
CO09 (The device object ID). For example, AEX-BAC-01050001.
If one writes the device object name manually through BACnet, the auto-build function will automatically be disabled (CO15 set to 0 or 1). In this
case, the auto increment function will not have an effect on the device object name, only on the device object ID.
