OVERVIEW / TABLE OF CONTENTS

Overview
The ceiling mounted Cassette units effectively make each area served an independent controlled temperature zone. Through thermostatic control of operations, conditions can be varied to suit diverse requirements or activities. Optional fresh air intakes are available to provide outside air for ventilation into the space.
Cassettes are available in a choice of three models: DX cooling, heat pump, or chilled water cooling. Optional heating can be provided as electric heat or hot water, depending on the model.
This versatility eliminates compromising architecture or design. Important cost savings are often realized during building modernizations, as existing piping and/or wiring can frequently be reused.
Design techniques are incorporated in every Airedale by Modine Cassette to reduce noise levels to a minimum. These techniques include low blower speeds, rigid panel and cabinet construction, and sound-absorbent cabinet insulation.
For individual comfort, Cassettes are available with electromechanical or micro-processor based controls.
The microprocessor controller includes an infrared transmitter which enables room conditions to be maintained at a user defined setpoint.
The Cassettes are also available with Carrel microprocessor controls and network cards to allow units to be connected to a Building Management System.
MODINE CSD Ceiling Cassette Ductless Mini-Split and Chilled Water - Logo The Modine Breeze® AccuSpec is the fastest way to generate performance data based on actual job conditions. The Breeze® AccuSpec program is a web-based sizing and selection program. The program provides a series of step-by-step questions that allow for the easy configuration of Airedale by Modine products. After a model has been configured, the program can generate Submittal Schedules, Submittal Data (including performance and dimensional
drawings), and Specifications.

Digit 8: Control Code (CC)
C = Modine Controls System
The unit shall be fitted with a programmable microprocessor controller designed to operate the unit according to pre-engineered control strategies.
The Carrel controller requires a wall sensor, wall stat or network interface card.
E = Electro-Mechanical Controls
The unit shall be factory wired with an electro-mechanical control system that includes the necessary relays and safety switches for proper unit operation. Terminal strip provide at the unit for the wiring of a 24V wall mounted thermostat required for unit operation.
The unit shall include terminals for remote start/stop of the unit. The unit is enabled when contact between the terminals is closed.
M = Microprocessor Controls
A custom designed microprocessor is fitted to the cassette to enable room conditions to be maintained at a user defined setpoint. Communication to the controller is by a hand held infrared transmitter.
The microprocessor monitors indoor coil temperature and return air temperature. The receiver contains a self diagnostic feature. When a low indoor coil temperature is detected the cooling action is stopped. If a sensor fails then an alarm is displayed on the fascia-mounted receiver.
The infrared transmitter is used to switch the unit ON/OFF, change temperature settings, fan speed, operating mode, and to toggle the motorized air sweep (where fitted). The microprocessor also has a built-in clock with a timer. The timer can be activated to provide ON/OFF unit operation. Note this is not a night set back or occupied/unoccupied control function.

STANDARD FEATURES
Construction
Cases are manufactured from lightweight galvanized sheet steel with integral fan mounting rails for added strength. Fire resistant foam insulation is fitted internally to provide both thermal and acoustic insulation.
Fan
Backward curved centrifugal fans are statically and dynamically balanced for quiet operation. Fan impellers are made from either aluminum or fire retardant plastic for lightweight and corrosion resistant operation. Fans are driven by an enclosed multi-speed
external rotor motor allowing good heat dissipation and an increased motor efficiency. Fans come complete with thermal overload protection and sealed-for-life lubricated bearings.
Condensate Pump
A condensate pump and check valve are fitted to carry condensate water out of the unit and stop water from flowing back into the condensate tray. The pump is fixed to a mounting bracket which can be withdrawn from the side of the chassis and incorporates an inspection hole to allow a visual check of the pump during operation. A float switch is fitted to stop the cooling action should the pump become blocked or fail.
Air Vanes
Air outlet vanes are designed to prevent condensation from forming. Vanes are manually adjustable on model sizes 08 and 12. The vanes on all other model sizes are driven by an electric motor. Motorized air vanes can be set to auto sweep or can be stopped in a fixed position. Polystyrene blanking pieces are supplied with Cassette packing so that up to two fascia discharge slots can be blanked off.
Alarm Status Relay
The unit shall include a relay for unit failure notification. In addition, a normally open contact is available for field connection.

ACCESSORIES – FIELD INSTALLED

FIELD INSTALLED ACCESSORIES
Fresh Air Duct Collars
The Cassette chassis features two or three fresh air knockouts depending on model size. Any number can be removed to allow fresh air to enter the unit. A duct collar is available for fastening to the unit to allow connection of a 3” flexible duct. A replacement filter is included with fresh air duct collars to aid in balancing the amount of return air and fresh air delivered to the unit’s coil. Supply Air Duct Collars A limited amount of conditioned air can be ducted from the unit by removing the branch duct knockouts (up to 2 per unit) and connecting flexible ducting. For model sizes 08 and 12, there are a total of three knockouts positioned on three of the unit sides (one per side). For all other model sizes, a total of four knockouts are available and are arranged in pairs along two of the unit sides (two per side). A duct collar is available to allow connection of a 5” or 6” (depending on units size) flexible duct to the Cassette.
On model sizes 08 and 12, it is recommended that only one of the three branch duct knockouts are utilized, due to the small capacity of the unit. Shroud A sheet metal shroud is available to cover the unit housing when the unit is not mounted in a drop ceiling. Painted Sky White with hammer tone finish.
Figure 6.1 – Duct ShroudMODINE CSD Ceiling Cassette Ductless Mini-Split and Chilled Water - Duct

Control Valves
For control of chilled water or hot water flow, a three-way, three port diverting type valve or a two-way, two-port control valve is supplied loose for on site installation. Actuation is via a 24V signal from the unit’s electrical panel.

  • Two Position Spring Return Control Valves
  • Two Position Spring Return Control Valves with Two Shut Off Valves (package)

On a four pipe system where two-way valves are specified, the chilled water valve will be a normally closed type. The hot water valve will be a normally open type. Where three-way valves are specified, the same type valve will be supplied for both coils and
should be installed normally closed to the coil in the case of the chilled water coil and normally open to the coil in the case of the hot water coil.
On a two pipe changeover system where a two-way valve is specified, a normally open valve is supplied. Where a three-way valve is specified, this should be installed normally open to the coil. In both cases, a pipe mounted changeover thermostat is factory supplied and shipped loose for field installation.
The changeover thermostat is used to monitor water supply temperature and allow action of the valve accordingly.
Condensing Unit (for DX or Heat Pump units) Refer to Breeze submittal for details.
Low Ambient Kit (Use with Condensing Units)
Fan speed control for compressor operation down to 0°F outside temperature.
