External Wiring
Alarm Wiring
The alarm contact closes whenever the
Prestige is in a soft or hard lockout. This
dry contact can be connected to an external
monitoring system or other indicator to alert
the operator that the Prestige is locked out.
1. Connect the external monitoring device to
the line voltage terminal strip on the wiring
panel below the PRESTIGE control mod-
ule, as shown in Fig. 19 on page 29.
The alarm contact is fused with a 2.5A
fuse located in the terminal strip. An iso-
lation relay is required if the external
monitoring device draws more than 2.5A.
Low Voltage Connections
Line and Low Voltage wiring should be
separated to prevent possible electrical
noise on the low voltage circuits. Line
and Low Voltage wiring should use sepa-
rate electrical knockouts on the PRES-
TIGE cabinet and should remain sepa-
rated inside the PRESTIGE.
CH call connections to the PRESTIGE
require a dry contact with no external
voltage present. Ensure no external volt-
age is present on each set of wires before
connecting to the PRESTIGE. If external
voltage is present, the use of an isolation
relay is required to prevent damage to the
Trimax controller.
Thermostat Wiring
The Trimax control has two thermostat call inputs
for multiple zone / temperature systems. This
allows each call to have its own outdoor reset
curve and maximizes the efficiency of the system.
Simultaneous CH1 and CH2 calls will
result in the PRESTIGE operating at the
highest target temperature. The use of a
mixing device on the lower temperature
zones such as the ACV-Triangle Tube
Optima Series SMV Control may be
required to protect the lower tempera-
ture zones from damage.
1. Connect the room thermostat or dry contact
end switch to the low voltage terminal strip
on the wiring panel below the PRESTIGE
control module, as shown in Fig. 19 on
page 29.
2. Follow thermostat manufacturer’s instruc-
tions for proper installation. Thermostat
should be located on an inside wall away
from any heat or cold influences such as
drafts, lights, fireplaces, etc.
3. Set the thermostat anticipator (If applica-
ble) as follows:
- Set for 0.2 amps when wired directly to
the PRESTIGE.
- Set to match the electrical power
requirements of the connected device
when wired to zone relays or other
devices. Refer to the relay manufactur-
er’s specifications and the thermostat
instructions for additional information
on anticipator setting.
The use of power stealing thermostats
which draw their power from the PRES-
TIGE can lead to erratic or unpre-
dictable operation.
