Temperature and Humidity Sensor Maintenance
The temperature and humidity sensor require very little maintenance. Periodically check the aeration slits on the
sensor to make sure that air can flow freely through, without obstructions due to impurities or dust. If cleaning is
required do not use ethyl alcohol, hydrocarbons (petrol), ammonia and derivatives. Use neutral detergents and
water.
7.29.1
Disposal of Temperature and Humidity Sensor
If the sensor is not returned to Data Aire, the sensor is made up of electrical components, plastic parts and metal
parts. Do not dispose of the device as commercial waste. All the parts must be disposed of according to your EPA
or local/national applicable disposal codes.
NOTICE
. Replacement temperature and humidity sensor must be the same
model and type as the original. Replacement temperature and humidity sensor
may be ordered from the Data Aire Parts department. Contact Data Aire Parts
Department for details. Other source or equal sensor may void any warranty
and may cause issues.
Mini-dap4 or dap4 Controller Replacement
When a Mini-dap4 or dap4 replacement controller is ordered from the Data Aire Parts department, the controller
is programmed and set to the original settings “as shipped” from the factory. If field adjustments to the settings
have been made, these must be recorded to be reloaded after the new controller is in place and operational.
1.
Turn OFF all remote electric power source to unit before maintenance or servicing.
2.
Use lock-out tag-out protection.
3.
Record all connection to the Mini-dap4 or dap4 controller. Use this information and data for rewiring the
replacement dap4. Often taking a picture of the original connections is helpful when rewiring.
4.
An electrical diagram of the Mini-dap4 or dap4 connections will come with the new controller to assist in
making the proper connections.
5.
Unplug the existing connections.
6.
The controller is DIN rail mounted so remove the controller using a screwdriver to release the mounting
clips along the top and bottom sides.
7.
Mount the new controller to the existing DIN rail using a flat blade screwdriver to actuate the mount clips
along the top and bottom sides. Make sure the new controller is securely fastened to the electrical panel.
8.
Plug the existing connectors to the new controller using the recorded information and pictures. Also use
the provided electrical diagram as additional guidance.
9.
Check all the wires are tightly fastened to the Mini-dap4 or dap4 connectors.
10.
If replacing the original display with the new display, disconnect the telephone cable type connector and
remove the display.
11.
Mount the new display using the original fasteners and plug the telephone cable type connector into the
new display.
12.
Always use the factory provided display cable. This cable looks like a telephone cable; do NOT replace it
with a telephone cable.
13.
Check all the wiring connections before restarting the unit. Refer to unit wiring diagram.
