Controllability

The Zehnder ComfoAir units have a unit mounted controller allowing you to adjust all settings and the unit has additional control options including Phone App and demand control sensors

App Control

With the Optional use of the Zehnder Comfo Connect LAN C enables the connection between the ventilation system and the Comfo Control app for iPhone and android devices.

Key Benefits

• Control and monitor the ventilation system via the Comfo Control app
• Control ventilation flow rate, temperature profile, temporary high-speed setting and external sensor set points
• Monitor ventilation flow rates, temperatures and external sensors
• 7 - day flow rate programmer
• Access the ventilation system remotely from anywhere in the world
• Service and Maintenance alert direct to your phone

🕹️ Wall Controllers (Optional):

• Comfo Sense C67 – Digital 4-speed controller with Co2 & humidity sensor support.
• Comfo Switch C67 – LED controller for speed adjustment & service alerts.
• Comfo Control RFZ – 3-speed wireless controller (requires Comfo Sense C67 or RF-PCB).

Option Box

With the optional Zehnder Option Box will enable the connection between the ventilation system and various other external components.

• 4 x 0-10v inputs
• Volt free Contacts
• Post Heater integration
• Comfo Fond LQ or Sub-Soil heat exchanger integration
• External filter alert integration
• Fire Alarm integration

Co2 / Humidity wall Sensors

An optional wireless room mounted Co2 or Humidity sensor is available that will boost the units speed when required through the Zehnder Comfosence controller or RF -PCB

An optional wired room mounted Co2 or Humidity sensor is available that will boost the units speed when required through the Zehnder Option Box

KNX / BMS Control

The optional Comfo Connect KNX C will enable the connection between the ventilation system and the KNX protocol and BMS integration is also possible through this option

RF-PCB

The Zehnder RF-PCB enables the CCRFZ (655 000 755) controller to be used with the ventilation system without the need for the Comfo Sense C67.

Integral Humidity Sensor

The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise.

Comfort Cooling

The Zehnder Q600 has the option of using a Comfo Cool unit that will provide comfort cooling on warm days

The Zehnder Comfo Cool Q600 is an air temperature device designed to help reduce the risk of overheating in homes. It combines with the ComfoAir Q600 and compliments its features to ensure it automatically activates and deactivates to provide a comfortable, healthy and energy-efficient indoor climate.

• Cooling is automatically activated by a user defined comfort temperature in combination with monitoring both intake air and internal air temperatures
• Equipped with a compression cooling system, as is used in refrigerators to reduce the temperature, in this case of the incoming supply of filtered air to provide 1.5kW of cooling capacity
• Differs from traditional air-conditioning by using the air performance of our MVHR system to deliver the available cooling power

Construction

The Zehnder Q range are manufactured of airtight and noise absorbing EPP with a plastic front cover

Motors

Filtration

• 2 x G4 filters are fitted to the unit that are easy to replace
• Optional F7 to air supply

Maintenance is easy with the warning indicator on the start-up wizard to indicate when filters may need attention or changing.

Summer By-Pass

The Zehnder Q range of units have a 100% summer by-Pass

Low Noise Levels

With airtight, aerodynamic and sound absorbing construction with perfectly balanced fans the noise levels are ultra quiet

Heat Exchanger

The Highest performing heat recovery exchanger that can recover up to 96% of otherwise lost heat

Frost Protection

The unit has a frost protection programme

Optional Pre Heater

The intelligent pre-heater adapts its operation taking into consideration temperature, air flow and humidity to ensure consistent supply air temperature is achieved no matter what is going on outside. Thanks to its large surface and delta shape, the level of pressure loss is negligible – and that also reduces the power consumption for the best possible energy efficiency

Orientation

The Standard unit can be changed from Left- or right-hand configuration through software alone, with no mechanical alteration or alternative configuration of unit is required

The Heater units can be right or left-handed and correct orientation should be checked before purchase

Mounting

The units are supplied with a wall mounting bracket and there is an optional floor stand

Warranty

Zehnder offer a 2-year warranty but can be extended to 6 years by registerable through Zehnder Website within 6 months of purchase (Homeowner registration | Zehnder Group UK)

Approvals

The Zender Q range units are passive house approved and SAP appendix Q listed
