ThermeXa 2025 is an advanced controller that allows full management of your ventilation unit, both locally and remotely via a dedicated app. It supports EC (PWM) and AC (relay-based) fans with smooth, percentage-based adjustment of supply and exhaust airflow.

Exhaust fan output (AC or EC 230V)
Supply fan output (AC or EC 230V)
Bypass control output
230V AC power input
MODBUS output to touch panel (RS485)
PWM3 for supply EC fan, PWM4 for exhaust EC fan
Inlet temperature sensor
Outlet temperature sensor
Supply air temperature sensor
Exhaust air temperature sensor
👷 Supported components:
2 fan motors: EC (PWM) or AC
Automatic or manual bypass (heat recovery switch)
The controller offers multiple predefined modes that automatically adjust the supply and exhaust fan speeds:
Party
Ventilation
Open window
Empty house
1, 2, 3 or 4 persons
Off
Each mode allows individual speed compensation (separately for supply and exhaust) within the range of 0–100%.
🌐 Wi-Fi Configuration:
Support for dynamic (DHCP) and static IP
Option for remote connection via the mobile app
🌡️ Climate Settings:
Summer mode based on set temperature (e.g. >19°C)
3 reactions to summer temperature exceedance:
Normal operation, Off, Every 15 minutes
Setting minimum and maximum supply air temperature
Fireplace mode (reduces fan speed, e.g. by 10%)
🧬 Supply Air Temperature Control:
Regulation based on:
Room temperature
Supply air
Exhaust air
🌨️ Heat Exchanger Defrost Functions:
Defrost activation temperature
Method: turn off supply fan, open bypass
Minimum air temperature before the exchanger
Ground Heat Exchanger (GWC) Support:
Summer mode (>18°C) and winter mode (<15°C)
Programmable operating and regeneration time
Kitchen hood: automatic speed reduction
Bathroom: increased exhaust speed
📡 Connection to Touch Panel (optional):
Additional data: temperature, pressure, humidity
RS485 communication (4 wires: GND, A, B, 5V)
Option for remote automatic updates via Wi-Fi
⚠️ Lack of a touch panel does not limit the basic functionality of the controller.
