Engineering Guide Speciﬁ cations cont.

torque 5-speed ECM is available on model sizes 022-072. An

optional 3-speed PSC blower motor is available on all single speed

models. The blower motor shall be isolated from the housing by

rubber grommets. The motor shall be permanently lubricated and

have thermostatic overload protection. Variable speed ECM and

5-speed ECM motors shall be long-life ball bearing type.

Electrical

A control box shall be located within the unit compressor

compartment and shall contain a 75VA transformer, 24 volt activated,

2 pole compressor contactor, circuit breakers for protecting loop

pumps, terminal block for thermostat wiring, and solid-state controller

for complete unit operation. Electromechanical operation WILL NOT

be accepted. Units shall be name-plated for use with time delay fuses

or HACR circuit breakers. Unit controls shall be 24 volt and provide

heating or cooling as required by the remote thermostat/sensor. An

Aurora, a microprocessor-based controller, interfaces with a multi-

stage electronic thermostat to monitor and control unit operation

shall be provided. The control shall provide operational sequencing,

blower speed control, blower failure, high and low pressure switch

monitoring, freeze detection, hot water limit thermistor sensing,

condensate overflow sensing, auxiliary heat staging, lockout mode

control, hot water and loop pump control, LED status and fault

indicators, fault memory, field selectable options, and accessory

output. The Lockout signal output shall have a pulsed option so that

DDC systems can read specific lockout conditions from the control.

The optional Aurora Advanced Control shall also feature an

Energy Monitoring Package that will provide real time total power

consumption, compressor monitoring, On Peak input signal for

utility controlled demand programs, intelligent hot water generation

with user adjustable temperature limit, loop pump linking for

multiple units driving a common flow center and up to two optional

home automation inputs to drive dedicated alarms for sump

pump, security system, and smoke/CO2 or dirty air filter sensors.

Optional Refrigerant and Performance Monitoring kits to provide

real time data including refrigerant superheat and subcooling, as

well as heat of extraction/rejection capacity data. The capability for

communicating to advanced IntelliZone2 zoning packages with up

to 6 zones (Variable Speed), 4 zones (Dual Capacity), or 2 zones

(Single Speed) shall also be provided with complete fault and

information display on the zoning MasterStat.

A detachable terminal block with screw terminals will be provided

for field control wiring. All units shall have knockouts for entrance

of low and line voltage wiring. The blower motor and control box

shall be harness plug wired for easy removal.

An optional Aurora Interface Diagnostic (AID) Tool shall

communicate with the Aurora control allowing quick and easy

access to setup, monitoring, and troubleshooting of any Aurora

control. The device shall include the features of ECM airflow setup,

fault description and history, manual operation capability, sensor

readings, timings, and other diagnostic tools.

Optional IntelliStart

installed for use in applications that require low starting amps,

reduced compressor start-up noise, off-grid, and improved start-

up behavior. IntelliStart shall reduce normal starting current by up

to 60%.

Piping

Supply and return water connections shall be 1 in. [25.4 mm] FPT
