Applications
Specifically developed for AC of commercial premises
i.e. offices, motels/ hotels, restaurants and retail outlets

AIR FLOW SELECTION

If air returning to the indoor coil is regularly expected to be above 50% relative humidity then the coil face
velocity should not exceed 2.5m/s (refer air flow graph page 8)

Consideration must be given to selecting an airflow and coil face velocity that avoids water carry - over
problems i.e. in high humidity (tropical/subtropical) conditions or when heavily moisture laden fresh air
is introduced

Applications using complete or high proportion of fresh air should be discussed with a Temperzone sales
engineer to establish the correct selection of unit

FEATURES
Refrigerant R410A circuit. This also allows for reliable operation Outdoor & indoor coil fins are epoxy coated
R410A used which has zero ozone depletion in Cooling Mode at ambients below 20°C, for extra protection in corrosive

SYSTEM PROTECTION FEATURES OPA 186/201 DIGITAL VERSIONS

1. HP and loss of refrigerant protection Digital Scroll Compressor
2. Anti rapid cycle timer and internal overload for compressor ‘Digital’ systems include a digital scroll compressor. The digital
protection version of this unit provides a variable capacity ability that enables
3. Circuit breaker protected control circuits closer control of room temperature. This is achieved by avoiding on/
4. Automatic de-ice cycle provides de-ice control during heating off cycling of the compressor. These compressors have proven very
cycle under low ambient conditions reliable because of their design simplicity. Electrical harmonic noise
5. Frost protection on cooling cycle is very low.
6. Sensor fault indication
7. Crankcase heater prevents liquid refrigerant condensing in the Extended Capability
compressors during the “off” cycle Digitals are particularly suitable for applications requiring full or high
8. Compressor minimum run time to ensure oil return proportions of fresh air, VAV, close control. Supply air temperature
control is also possible using BMS or other controls.

REFRIGERATION SYSTEM Control Option

Each high efficiency scroll type compressor is hermetically sealed The system is set up for the compressor to be controlled variably by
quiet running and supported on rubber mounts to minimize a 0–10 volt DC signal that can be supplied either by a BMS system, a
vibration sophisticated controller or temperzone’s optional TZT-100
Controller.
Factory charged with HFC-410A (R410A) refrigerant. Accurator
expansion devices for precise control the flow of refrigerant
OPTIONAL EQUIPMENT
WIRING 1. Anti-vibration mounts

2. TZT-100 room temperature controller

The electrical supply required is 3 phase 342-436V ac 50Hz with
neutral & earth

The compressor crankcase heater requires a 24hr power supply

The unit’s control panel is fully wired ready to accept the main power
supply. Each system conforms with emission standards EN 55014-1,
EN 60335-1 and EN 60335-2-40.

AIR HANDLING
Note: Airflows are for a dry coil. Reduce airflow by 5% in high moisture removal conditions. In a free blow or low resistance application,
beware of exceeding indoor fan motor’s full load amp limit (refer back page). Air flows given are for units installed without filters.
