3.6 Remote Shutdown

Every Data Aire evaporator has remote shutdown contacts. These are 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.

The remote shutdown contacts are always terminals #1 and #2 on the terminal block designated

TB1. The unit will ship with a factory wired metal jumper clip that connects terminal #1 to terminal

#2. Remove this clip prior to installing the ﬁ eld wires.

3.7 Remote Alarm Contacts

The DAP

-III microprocessor control provides a remote alarm output contact that can be ﬁ eld

accessed on terminals # 11, 12 and 13 of terminal block TB2. Terminal # 12 is a Normally Closed

(NC) open on Alarm dry contact. Terminal # 13 is a Normally Open (NO) close on alarm dry

contact. Both are intended to be used in a control circuit not exceeding 4 amps at 24VAC.

These programmable output contacts will close or open on a failure and will remain open or closed

until the alarm is no longer present. Three additional alarm output contacts are available and require

the Relay Module. The terminal designations for these alarms contacts are as follows:

# 40 – Remote Alarm 2 (Common)

# 41 – Remote Alarm 2 (Normally Closed)

# 42 – Remote Alarm 2 (Normally Open)

# 43 – Remote Alarm 3 (Common)

# 44 – Remote Alarm 3 (Normally Closed)

# 45 – Remote Alarm 3 (Normally Open)

# 48 – Remote Alarm 4 (Common)

# 49 – Remote Alarm 4 (Normally Closed)

# 50 – Remote Alarm 4 (Normally Open)

3.8 Remote Sensors

Remote sensors are optional. Although existing unit mounted 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 ﬁ ve wires,

these should be a twisted, shielded cable.

3.9 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 powered. While no outside power source

is required, ﬁ eld piping is still a requirement.

Condensate pumps are wired to display a “High Condensate Water Level” alarm. The wiring for

this must be done in the ﬁ eld on pumps that ship loose. Factory mounted pumps come pre-wired.
