1. INTRODUCTION
The SlimZone Classic (2701-001/2701-006) zone panel is designed to control conditioned air in separate zones using a single heating and cooling unit. Model 2701-001 controls up to 3 zones; model 2701-006 controls up to 2 zones. SlimZone is compatible with both single stage heating and cooling units and single compressor heat pumps with auxiliary heat. The temperature of each zone is controlled by its own individual thermostat and duct mounted motorized damper assemblies which control the distribution of conditioned air into each zone. All zone thermostats and dampers are wired directly to the SlimZone Classic control panel. The control panel is wired to the HVAC equipment. Power to the zone thermostats and motorized dampers is provided by the control panel. A dedicated 24VAC, 75 VA transformer is required to power the control panel.
1.1. IMPORTANT NOTE
IT IS IMPORTANT THAT YOU READ AND UNDERSTAND THIS MANUAL SUPPLIED WITH THE SLIMZONE
CLASSIC, AS WELL AS THE HVAC EQUIPMENT MANUFACTURER’S INFOR-
MATION, BEFORE INSTALLING THE SYSTEM.

1.3. SAFETY INSTRUCTIONS
• Sudden operation may cause serious injury from moving parts. Leave power disconnected until installation is complete.
• Sharp edges may cause damage to wires. Use care during the installation.
• Installation must be done in accordance with all local applicable codes and regulations.
• Installer should touch a grounded metal object before handling the SlimZone Classic com­ponents and thermostats to avoid potential loss of internal computer programs due to static discharge.

2. APPLICATION AND DESIGN CONSIDERATIONS
a. Air conditioning control systems require the air handling equipment be properly sized for
the application; otherwise, satisfactory temperature control may not be realized.
b. Oversizing of HVAC equipment is not recommended. In most cases it is better to slightly
undersize than oversize.
c. Extra consideration should be given in applications that require large amounts of cooling
in cold weather, such as buildings with a center or core area.
d. Hot gas bypass should be considered on some commercial systems. e. If the HVAC unit is supplied with an economizer, it is recommended that the economizer
package be equipped with a relief air damper.
f. The SlimZone Classic requires the use of motorized zone dampers, such as the A 24VAC 2
wire (powered closed, spring open) or 3 wire (powered closed, powered open) configuration.
g. The pressure drop across typical zone dampers is negligible and normally not a factor
when sizing or calculating branch duct CFM.
h. Typical zone control dampers are designed to work only with low pressure systems (1.0"
WC or less).
i. Balancing dampers should be installed ahead of all motorized zone dampers. j. Zone dampers should be installed 10ft. (3m) back from discharge grille when possible.
k. Flex or lined duct is recommended on the last 5ft. (1.5m).
l. A bypass damper must be installed on all systems of three (3) zones. Some two (2) zone
systems may require a bypass damper.
m. The thermostats and motorized dampers may be located up to 300ft. (90m) from the
control panel when 18AWG copper thermostat wire is used.
n. This system requires standard electromechanical or electronic heat/cool thermostats. Do
not use heat pump thermostats because a call for compressor from the thermostats will be recognized by the panel as a cool only call. The control algorithm in this panel is configured such that heat pump thermostats are not required.
o. The mode of equipment operation at the control panel is first determined by the signals
present on the C and H input terminals of Zone #1, then on the mode of operation of the zone thermostat(s).
p. To comply with Class 2 wiring code, the maximum load allowed to be switched by the
output terminals is 2.5 Amps.
q. All outputs are protected by a current limiting device.
r. System wires should be tagged to match the panel terminal designations.
s. The addition of equipment heating and cooling limits, as provided by the HILO-200, is
strongly recommended and will greatly help in preventing temperature swings as well as constant heating/cooling changeover.
t. All zones served by a panel should have the same basic load characteristics.
u. References to typical dampers in this manual are Robertshaw model dampers.
CAUTION
• To avoid short cycling of equipment, always disconnect HVAC equipment from the control panel before overriding time delay.

3. COMPONENT REQUIREMENTS
3.1 BASIC SYSTEM
The basic system consists of the main SlimZone Classic control panel and the components required to support it.
ITEM QUANTITY CONSIDERATIONS
2701-001 or 2701-006 1 controls 3 or 2 zones
4 wire heat/cool thermostat 1 per zone use standard nonshielded 4 conductor
18AWG copper wire
Motorized zone dampers 1 per zone (minimum) use standard nonshielded 2 or 3 (2 or 3 wire) conductor 18AWG wire
Barometric bypass damper 1 BP-10 up to 3 tons capacity or
OR BP-12 5 tons capacity
Motorized bypass damper 1 use standard nonshielded 3 conductor
18AWG wire; requires 24VAC transformer and static pressure controller (refer to section 4.6.3)
24VAC transformer 1 for control panel 75 VA; refer to section 3.3 for load
considerations
Table 3.1: SlimZone Classic Component Requirement
3.2 THERMOSTATS
SlimZone Classic requires any conventional electromechanical or electronic 1 heat/1 cool auto or manual thermostat.
3.3 SIZING TRANSFORMERS
To avoid unsatisfactory operation DO NOT power this control panel with the HVAC equipment transformer. The rated voltage for the SlimZone Classic is 20-30 VAC, 24 nominal. A dedicated field supplied 24VAC, 75 VA transformer is recommended to power the control panel, which in turn provides power to the zones including up to a total of 5 dampers. Typical zone dampers require a maximum of 12 VA each. Where damper loads exceed 5 dampers at 12 VA per damper, install a relay to switch the extra load.
3.4 SIZING DAMPERS
It is important that dampers be sized according to system ductwork specification (CFM) and balanced in compliance to SMACNA, ACCA and ASHRAE guidelines in order for the control system to properly control comfort in each zone. Typical dampers are non­modulating and are available in 2 wire (powered closed, spring return to open), or 3 wire (powered closed, powered open) configuration. The pressure drop across typical control dampers is negligible and normally not a factor when sizing or calculating branch duct CFM. Typical dampers are designed to work with low pressure systems (1.0" WC) or less.

4. SYSTEM INSTALLATION
4.1 REMOVAL AND INSTALLATION OF DOOR
Installer should touch a grounded metal object before handling the control panel to avoid potential loss of operation due to static discharge. The door is hinged on the left
side.
Open the door by gently pulling on the bottom
right corner. Apply finger pressure only. The door may be removed once opened by applying a slight backward pressure. Replace the door by hooking around the tabs on the left side of the base panel and snapping back into place.
