the client’s selected location in the controlled sp
ace. The combination remote temperature and humidity sensor is
connected to the control module via separate wiring which is also included with the system.
The dap4 and Mini-dap4 controllers allows recall and display of the high and low temperature, high and low
humidity, current percent of capacity and average percent of capacity for chilled water valve, compressor, reheat,
humidification, dehumidification, component runtimes for fan motor(s), reheat, humidification, and
dehumidification (if applicable).
See the separate dap4 or Mini-dap4 User Manual for detailed setup and operating instructions.
Auxiliary Control Wiring
The interconnection of auxiliary control wiring for remote heat exchangers (condensers and fluid coolers) requires
the connection of two (2) 18-gauge wires for installations up to 150 feet (45 m) or 16-gauge wires for installations
from 151 feet (46 m) up to 200 feet (61 m) from the electrical control panel of the indoor evaporator to the electrical
control panel of the remote heat exchanger.
Because of the wide variety of indoor evaporators and remote heat exchangers offer by Data Aire, the installing
contractor must refer to the electrical diagrams which are provided inside the electrical control panel of each unit
for the required auxiliary control wiring interconnection terminal points. Figure 10 - Typical Remote Heat Exchanger
Interconnection Points and Figure 11 - Typical Indoor Evaporator Interconnection Points show typical
interconnection points.
NOTICE
Check the wiring connections in the electrical control panel to ensure
they are tight. Screw terminals may become loose in transit. Tightening of
wiring connections is the responsibility of the installing contractor.
