Remote Shutdown
Every Data Aire evaporator has remote shutdown contacts points available. This is intended for a
fi eld supplied dry contact or switch to be wired across two terminals. When the contact or switch
opens, the control circuit power is interrupted and the unit shuts down, including the control panel.
The control circuit is 24 VAC and the fi eld provided contact or switch should have a minimum rating
of 10 amps. A minimum wire size of 18 gauge wire is recommended. Check wiring diagram for
location of the terminals.

Remote Alarm Contacts
If the Mini DAP II microprocessor control panel is ordered with the optional summary alarm module,
a remote alarm output contact can be fi eld accessed on terminals #14 and #15 of terminal block
TB1. This is a Normally Open, Close on Alarm, dry contact, intended to be used in a control circuit
not exceeding 5 amps at 24 VAC. This output contact will reverse position on a failure and remain
reversed until the alarm is no longer present.

Remote Sensors
The Mini DAP II panel normally comes with sensors mounted in the panel. Although these existing
sensors can be removed for remote mounting, the remote sensor option provides a more convenient
means of fi eld installation. This is because the sensors are already connected to a predetermined
length of cable and come mounted in a remote sensor enclosure. The temperature and humidity
sensors require a total of six wires. This should be a twisted, shielded cable.

Condensate Pumps
Condensate pumps which ship loose normally require a separate source of 110 volt power. Always
check the pump power requirements before connecting power. Condensate pumps are available
in other voltages.
Condensate pumps may also come unit mounted and wired in the unit as a factory option. While no
outside power source is required, fi eld piping is still a requirement.
