1.0 PRODUCT FEATURES
1.1 Standard Product Features
The Mini-Mate2 is a temperature/humidity control system designed to be installed above a ceiling
grid system. The unit is available as a split system evaporator to be matched with an Indoor Centrif-
ugal Fan Condensing Unit, Outdoor Prop Fan Condensing Unit, or Indoor Water/Glycol Condensing
Unit. A self-contained Chilled Water Fan Coil is also available.
1.1.1 Controls
The Mini-Mate2 system includes a wall-mounted display panel with a liquid crystal display (LCD)
screen and a 7 membrane keypad. The control is menu-driven for ease of use. Figure 24, Section 3,
depicts the complete menu tree for the control. All control setpoints and alarm setpoints are program-
mable.
1.1.2 Evaporator System Components
DX Evaporator Section
The evaporator section includes the evaporator coil, thermostatic expansion valves, filter dryers, and
blower. The evaporator coil is constructed of copper tubes and aluminum fins and is designed for the
high sensible heat ratio required for electronic equipment. Room air circulation is accomplished by a
double inlet, belt driven centrifugal blower that has been dynamically balanced. The blower has self-
aligning bearings. Both the blower and motor have permanently lubricated ball bearings.
Chilled-Water Model
The Chilled-Water model is self-contained and is designed for use with an existing chilled-water loop.
It contains a chilled-water coil and a proportional modulating valve to control the flow of chilled
water.
1.1.3 Condensing Unit Components
The condensing unit is connected to the evaporator unit by four refrigerant lines and low voltage con-
trol wires. The condensing unit requires a power source and a power disconnect switch. A single point
power kit is available for close coupled (attached) units.
Air-Cooled Condensing Unit (Indoor Centrifugal)
The Air-Cooled Condensing units (MC models) include: 3-ton and 5-ton scroll compressors with motor,
belt-driven centrifugal blower, crankcase heaters, high pressure switches, condenser coils, and Lee-
Temp head pressure control with receivers.
Air-Cooled Condensing Unit (Outdoor Prop Fan)
Outdoor Air-Cooled Condensing Units (PFC models) include: 3-ton and 5-ton scroll compressors with
crankcase heaters, high-pressure switch, condenser coils, direct-driven propeller fan, and Lee-Temp
head pressure control with receivers.
Water/Glycol Condensing Unit (Indoor)
The Water/Glycol-Cooled Condensing units include: 3-ton and 5-ton scroll compressors with crank-
case heaters, high pressure switches, coaxial condensers, and regulating valves. Drycooler and pumps
are selected separately for glycol systems.
