Braemar TH & TG Series Zoning Setup and Spectrolink Control (SCC) Commissioning Guide


⚠️ Safety Notice – Gas Heating Products

This appliance must only be installed, commissioned, serviced and repaired by suitably qualified and licensed personnel.


Before commencing work, complete a task-specific risk assessment and ensure gas and electrical safety requirements, ventilation provisions, safe access, adequate service clearances and appropriate PPE have been considered. All work must comply with applicable regulations, standards and manufacturer requirements.


Particular care must be taken when working around gas systems, electrical components, combustion products, hot surfaces, moving parts, roof spaces, ceiling spaces and confined spaces.


Do not proceed if safe access, required clearances, ventilation requirements, confined space risks or appropriate safety controls cannot be achieved and maintained. 


Safety takes priority over diagnosis, repairs, installation schedules and customer expectations. If the task cannot be completed safely, it must not proceed until the risks have been adequately controlled.

Before You Start

Ensure you have access to:

  • Installation & Service Manual
  • Zoning Supplement Manual
  • Technical Bulletin A06/08
  • Home Owner's Manual

AS5601 requirements take precedence over all installation instructions.

SCC Compatibility

The Spectrolink Comfort Control (SCC) is compatible with:

  • Braemar TH & TG Series heaters
  • Braemar SPI systems (TA, TE)
  • Braemar MPI systems (TM, TE)
  • Breezair, Braemar and Coolair evaporative coolers using CPMD electronics
  • Refrigerated cooling systems

SCC Initial Setup

Important

The heater and cooler type must be configured within the first 15 minutes of powering the SCC.

If the SCC has been powered for more than 15 minutes:

  1. Remove the SCC from the wall plate.
  2. Disconnect the loom plug.
  3. Short the terminals on the black capacitor for approximately 30 seconds.
  4. Continue until the display is completely blank.
  5. Reconnect and power up.

Time and day will need to be reset. User settings are retained.

Set Heater and Cooler Type

With the SCC in HEAT mode and OFF:

  1. Press SET + AC MODE together.
  2. Select the heater type:

  1. Press SET to save.

Single SCC Zoning Setup

Enable Zones

  1. Select HEAT Mode.
  2. Turn SCC OFF.
  3. Press SET + ZONE 1.
  4. Select the required number of zones.
  5. Press SET.

Set Maximum Fan Speed

  1. HEAT Mode.
  2. SCC OFF.
  3. Press SET + FAN.
  4. Select fan speed 7–10.
  5. Press SET.

Set Individual Zone Fan Speeds

  1. HEAT Mode.
  2. SCC OFF.
  3. Press FAN + ZONE 1.
  4. Adjust the fan speed for each zone.
  5. Press SET after each adjustment.

Manual Zone Control

Open the SCC door:

  • Press a zone button to turn that zone OFF.
  • Press again to turn the zone ON.

Multi-SCC Zoning Setup

Requirements

  • One SCC per zone.
  • SCC must be physically located in the zone it controls.

Commissioning

  1. Configure maximum fan speed from the Zone 1 (Master) SCC.
  2. Press SET + ZONE 1 to confirm all SCCs are communicating.
  3. Set fan speeds for each zone as required.

Each zone can operate independently using its own temperature setting.

Thermostat Location Guidelines

Install the SCC:

✅ Approximately 1.5m above floor level

✅ Within the zone being controlled

Avoid:

  • Direct sunlight
  • External walls
  • Drafts
  • Heat-producing appliances
  • Supply air outlets

Outlet Airflow Guidelines

In-Ceiling Systems

Outlet SizeRecommended Airflow
150mm55–70 L/s
200mm85–100 L/s

Underfloor Systems

Outlet SizeRecommended Airflow
150mm40–50 L/s
200mm60–70 L/s

⚠️ Excessive airflow can result in increased noise and customer complaints.

⚠️ 200mm outlets are generally not recommended on heating-only systems.

Refrigerated Cooling Systems

For refrigerated cooling installations:

  • Select COOL 2 during commissioning.
  • Maximum fan speed is fixed at 10.
  • Heating zone configuration is used for cooling operation.
