11. COMMUNICATION PORTS

11.1 Several types of communication ports are available on the UC6.

Note 1: Connectors to the UC6 show R+/T+ for signal A, R-/T- for signal B.

 

11.2 Temperzone TZT-100 thermostat connection

The UC6 can connect directly to the temperzone TZT-100 thermostat using a shielded cable with two twisted pair wires 

suitable for RS85 serial communications. The drawing below shows connection details.

12. MAINTENANCE

  WARNING HAZARDOUS VOLTAGE. ENSURE ALL POWER SUPPLIES 

ARE ISOLATED BEFORE PERFORMING MAINTENANCE. FAILURE TO 

ISOLATE POWER CAN LEAD TO SERIOUS INJURY. 

12.1 Monthly

1.  Check air filters, if fitted, and vacuum or wash clean 

as necessary.

2. Check condensate drain for free drainage.
3.  Check compressor compartment for oil stains 

indicating refrigerant leaks.

4.  Check system operating pressures and history using 

PDG mini service interface tool fitted to all ECO 

machines

12.2 Three Monthly (or every 1200 hrs of operation)

Check the indoor unit’s indoor EC motor and plug fan 

operation and adjust if necessary, using PDG mini 

service interface tool fitted to all ECO machines.

12.3 Six Monthly

1. Check the tightness of electrical connections.
2. Check the tightness of all fans, motor mountings
3.  Check suction and discharge operating pressures 

using PDG mini service interface tool fitted to all ECO 

machines 

4. Check and or  Replace indoor air filters
5. Check condensate drain for free drainage.

12.4 Yearly

1. Check all refrigerant piping for chafing and vibration.
2. Check the operation of electric heaters, if fitted
3. Check air supply at all diffusers
4.  Check for excessive noise and vibration and correct  

as necessary.

5.  Check for insulation and duct damage and repair  

as necessary.

6.  Check system operating pressures and history using 

PDG mini service interface tool fitted to all ECO 

machines

7.  Remove lint and dust accumulation from outdoor  

coil fins with soft brush or low pressure water spray.

8. Touch up any paintwork damage to prevent corrosion.
