Why choose the Weston Climate Core ventilation unit?

• Heat recovery efficiency up to 97% - helps reduce the energy loss associated with ventilation.
• Energy-efficient EC fans – efficient and smoothly controlled ventilation.
• Automatic cold protection - helps ensure the device operates even at cold outside temperatures.
• Summer bypass – allows bypassing the heat exchanger with fresh outside air during warm weather.
• Flexible installation – the device can be installed vertically or horizontally and used with either left or right connection.
• Convenient maintenance - maintenance panels are located on both sides of the device.
• Thermal and acoustic insulation – 30–45 mm of internal insulation helps reduce heat loss and the spread of noise from the unit.
• A+ energy rating and compliance with EU EcoDesign requirements EU1253/2014 ErP2016 ErP2018
• 7-year warranty – added assurance for long-term use.

Control of the Ventilation System

For the Weston Climate Core heat recovery ventilation unit, you can choose CP2 or CP8 control panel. Both allow for convenient ventilation control and the use of Wi-Fi remote control via an app.

• fan speed control
• weekly work schedule
• boost and bypass mode
• Notification to clean or replace the filter

CP8 control panel

• 7-inch color touchscreen
• WiFi and smart app control
• automatic ventilation control based on CO₂, PM2.5, VOC, and humidity
• possibility of connecting external CO₂, temperature and humidity sensors
• Notification to clean or replace the filter
• Modbus RS485 connection with building automation
• Filter maintenance and replacement reminder
• More Precise Adjustment of Fan Speeds and Operating Modes
