Multi System Field Reference

This guide covers all the fields and options available when configuring multi system quotes in the Cooledge mobile app. Multi systems consist of multiple indoor units connected to a single outdoor unit, providing independent temperature control for different areas.

Overview

Multi systems (also called multi-split systems) allow multiple indoor units to connect to one outdoor unit. Each indoor unit can be controlled independently and may have different specifications. This guide details every configuration option available in the Cooledge app for accurate multi system quoting.

1. System Configuration

Multiple Indoor Unit Areas

Multi systems are configured with multiple indoor unit areas, each requiring individual setup:

• Area Names: Custom names for each area (e.g., "Living Room", "Bedroom 1", "Office")
• Individual Unit Selection: Each area gets its own indoor unit
• Independent Add-ons: Each indoor unit can have specific add-ons
• Per-Area Configuration: Pipe lengths, trunking, and drainage configured per area

2. Power Supply Configuration

Configure the electrical supply for the multi system (applies to the entire system):

Available Options:

• Not Set: No power option selected yet
• Reuse: Use existing electrical connection
• Reuse - Upgrade to RCBO: Reuse connection but upgrade safety switch to RCBO
• Existing Local Power Circuit: Use nearby existing circuit
• Existing Local Power - Electrical Capping: Use existing circuit with capping for neat finish
• New Dedicated Circuit: Install completely new dedicated electrical circuit
• Excluded: Electrical work not included in quote

Important Details:

• New Dedicated Circuit: Includes RCBO switch (residual current operated circuit breaker with overload protection) by licensed electrician
• Single Connection: Power supply configuration applies to the entire multi system
• Higher Amperage: Multi systems typically require higher capacity circuits than split systems

3. Outdoor Unit Mounting

Select how the outdoor unit will be mounted (single outdoor unit for all indoor units):

Available Options:

• Not Set: No mounting option selected
• Anti Vibration Rubber Mat: Standard rubber mat (usually included at no extra cost)
• Evocrete Slab: Concrete mounting pad for stable installation
• Adjustable Anti Vibration Feet: Height-adjustable mounting feet
• PVC Mounting Feet: Plastic mounting feet for elevation
• Brackets up to 2m: Wall or fence mounting up to 2 meters high
• Brackets above 2m: Wall or fence mounting above 2 meters high
• Brackets up to 2m (Stainless Steel): Marine-grade brackets up to 2m
• Brackets above 2m (Stainless Steel): Marine-grade brackets above 2m
• Roof Brackets: Specialized roof mounting (multi system specific)
• Treated Pine Timbers: Timber platform mounting (multi system specific)

Multi System Specific Options:

• Roof Brackets: For rooftop installations where ground mounting isn't feasible
• Treated Pine Timbers: Elevated timber platform for larger outdoor units
• Enhanced Stability: Larger outdoor units may require more robust mounting solutions

4. Indoor Unit Area Configuration

Each indoor unit area requires individual configuration:

Per-Area Settings:

Pipe Length Configuration:

• Default Length: 3 meters per area (included in base installation)
• Additional Length: Charged per meter beyond 3m per area
• Independent Routing: Each area's pipes can take different paths
• Reuse Option: Set to 0 if reusing existing pipework for that area

Trunking Configuration:

• Default Length: 2 meters per area
• Color Selection: Each area can have different trunking colors
• Individual Routing: Trunking requirements vary per area
• Reuse Option: Set to -1.0 if reusing existing trunking

Color Options (Per Area):

Choose from 23 available colors for each area:

Standard Colors:

• Surfmist (most popular)
• Evening Haze
• Shale Grey
• Dune

Additional Colors:

• Windspray, Wallaby, Jasper, Basalt
• Ironstone, Terrain, Monument, Classic Cream
• Paperbark, Pale Eucalypt, Woodland Grey, Deep Ocean
• Cottage Green, Manor Red, Night Sky, Sandbank
• Bushland, Wilderness

Internal Plastic Capping (Per Area):

• Length: Set in meters per area (0 = not required)
• Purpose: Covers internal pipework for neat finish
• Independent Configuration: Each area can have different capping requirements

Condensate Drain Configuration (Per Area):

Drain Location Options:

• Outside: Drain directly outside (most common)
• Garden / Lawn: Drain to garden area
• Downpipe / Floor Waste: Drain to existing drainage
• Reuse: Use existing drain connection

Condensate Pump (Per Area):

• Required: Toggle on per area if gravity drainage not possible
• When Needed: Indoor unit above drain point or long drain runs
• Individual Pumps: Each area can have independent pump requirements

5. Labor Configuration

Set installation time and crew requirements for the entire multi system:

Time Allowance Options:

• 0.5 Day: Half day installation (simple multi system)
• 3/4 Day: Three-quarter day installation
• 1 Day: Full day installation (standard multi system)
• 1.5 Days: Day and a half installation (complex multi system)
• 2 Days: Two day installation (large or complex multi system)
• Not Set: No time allocation set

Number of Installers:

• 1: Single installer (smaller multi systems)
• 2: Two installers (standard multi systems)
• 3: Three installers (complex multi systems)
• 4: Four installers (large commercial multi systems)
• Not Set: No crew size specified

Special Requirements:

• Long Ladder: Required for high installations
• Lifter Type:
  • Max 3.2m: Standard lifter
  • Above 3.2m: Heavy-duty lifter for high installations

Multi System Labor Considerations:

• Multiple Connections: Each indoor unit requires individual connection
• Complex Routing: Multiple pipe runs increase installation time
• System Commissioning: More complex than single split systems
• Crew Coordination: Larger crews often more efficient for multi systems

6. Removal Options

Configure removal of existing equipment:

Removal Types:

• No: No removal required (new installation)
• Indoor and Outdoor: Complete system removal
• Indoor Only: Remove indoor units only
• Outdoor Only: Remove outdoor unit only

Multi System Removal Considerations:

• Multiple Indoor Units: Removal complexity increases with number of units
• Refrigerant Recovery: Larger systems require more refrigerant recovery time
• Access Requirements: Multiple indoor units may be in different areas
• Disposal Coordination: Multiple units require organized disposal
