7.0 CONTROLS

7.1 DAP

III Microprocessor Control Panel

The standard controls on all Data Aire Series equipment is the DAP III microprocessor control

panel. This state-of-the-art control panel has a separate manual that goes into extensive detail

regarding functions, features, programming, and troubleshooting.

The DAP III microprocessor control panel has an entire manual dedicated to its use and operation.

This manual must be referenced to complete a thorough unit installation. Start-up is not complete

until the DAP III control panel settings are established.

7.2 Secondary Heat Exchangers

Most of the controls on remote condensers, condensing units, and ﬂ uid coolers consist of basic

electromechanical type components. Secondary heat exchangers have separate Selection Guide/

Operation and Maintenance manuals which give complete details on adjusting thermostat settings,

etc. Refer also to details in Section 3.5 within this manual.

7.3 Wiring Diagrams

Every Data Aire evaporator, condenser, condensing unit, or ﬂ uid cooler comes with a wiring

diagram. These diagrams are ‘ladder’- type schematics intended for service personnel. The intent

is to allow the technician to understand the wiring details associated with the electrical components

and how they interface with the DAP III control panel as well as peripheral equipment, including

secondary heat exchangers.

The wiring diagram in the evaporator will indicate ﬁ eld interface terminals to the secondary heat

exchanger. The internal wiring of the heat exchanger is found on a separate diagram which can be

found on the inside cover of the heat exchanger electrical box. Both diagram types are also placed

inside the shipping/warranty packet that is placed inside the evaporator.

Evaporator wiring diagrams will have a drawing number which starts out with the three letter

designation, “DAX”. An example of a typical diagram is DAX-S-603 N. Wiring diagrams for condensers

or condensing units start out with the three letter designation, “DRC”. An example of a typical diagram

is DRC-S-001. Wiring diagrams for ﬂ uid coolers start out with the three letter designation, “DFC”.

An example of a typical diagram is DFC-S-001.
