✨ Why choose ZTL?
The Mitsubishi range for people who want connected control.
Standard Plus takes the MHI experience beyond simple infrared control. It adds integrated wireless LAN, Smart M-Air control and more flexible scheduling while keeping the clean wall-mounted format.
Smart M-Air app
Control temperature, operating mode and schedules from a compatible smartphone or tablet.
Weekly scheduling
Set recurring comfort schedules rather than relying only on a simple daily On/Off timer.
Energy monitoring
Smart M-Air adds useful electricity-consumption and energy-management information for customers who want more visibility.
Outdoor Silent Mode
The Standard Plus range includes selectable Silent Mode settings to reduce outdoor-unit operating noise when required.
Strong efficiency
The supplied AC BRUM data for the quoted 2.5, 3.5 and 5.0 kW models is rated A++ for cooling and A++ for heating.
🌿 Filtration note: the supplied ZTL technical data lists the Allergen Clear Filter and Photocatalytic Washable Deodorising Filter as optional, not included as standard. We confirm any optional filtration requirement with the final model specification.
📐 Installation flexibility
More flexible than the advertised 2–3 m starting allowance.
The equipment can support longer refrigerant runs, but the AC BRUM starting prices are still based on a simple back-to-back installation.
2.5 kW ZTL
Our supplied data shows a maximum one-way refrigerant pipe length of up to 20 m.
3.5 kW ZTL
Our supplied data shows a maximum one-way refrigerant pipe length of up to 20 m.
5.0 kW ZTL
Our supplied data shows a maximum one-way refrigerant pipe length of up to 25 m.
Equipment capability is not the same as the advertised installation allowance. Longer pipe routes use more materials and labour and may increase the final installed price.
🧰 What's included?
Our standard installation, clearly explained.
The advertised price assumes a straightforward single-split job. We normally assess this remotely from room dimensions and photos.
✅ Standard starting price assumes
- ✓One indoor unit connected to one outdoor unit.
- ✓Back-to-back positioning on opposite sides of the same external wall.
- ✓Approximately 2–3 metres of refrigerant pipework.
- ✓Gravity condensate drainage with no pump required.
- ✓Straightforward access at normal working height.
- ✓Pressure testing, evacuation, commissioning and customer handover.
- ✓For most suitable single splits, power can normally be taken from a suitable nearby socket circuit via a local fused spur.
🟠 We review these before fixing the price
- ↗Longer or more complex refrigerant routes.
- 💧Condensate pumps where gravity drainage is not possible.
- 🪜High-level units or specialist access requirements.
- 🔩Non-standard mounting or unusual structural conditions.
- ⚡Additional electrical work where the existing circuit is unsuitable.
- 🔗Multi-split systems. These require technical review and a dedicated consumer-unit supply installed by an electrician at additional cost.

❓ Common questions
Before you request a ZTL quote.
Does ZTL have built-in Wi-Fi?
Yes. Integrated wireless LAN is part of the ZTL Standard Plus range, allowing Smart M-Air app control from a compatible phone or tablet.
Can I schedule the system?
Yes. ZTL supports weekly scheduling through Smart M-Air, and the supplied infrared controller also provides a 24-hour programmable On/Off timer.
Does ZTL include specialist air filters?
The supplied technical sheets used by AC BRUM list the Allergen Clear Filter and Photocatalytic Washable Deodorising Filter as optional. If filtration is a priority, tell us and we will confirm the exact equipment specification.
How quiet is ZTL?
The supplied 2.5 kW and 3.5 kW ZTL technical data reaches approximately 22 dB(A) at the lowest indoor sound setting. Exact sound levels vary by model and operating mode.
Which ZTL size do I need?
We size the unit from the room dimensions, glazing, insulation, ceiling height and heat load. The current AC BRUM sales options are 2.5, 3.5 and 5.0 kW.
Do I need a site survey?
Usually not for a straightforward residential installation. Room measurements, indoor and outdoor photos and a floor plan where available can normally give us enough information to quote remotely.
What warranty is included?
Our current offer includes a five-year parts warranty. Exact warranty conditions are confirmed with the final equipment and quotation.
