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.

Numbered Inputs and Outputs:

1. Exhaust fan output (AC or EC 230V)

2. Supply fan output (AC or EC 230V)

3. Bypass control output

4. 230V AC power input

5. MODBUS output to touch panel (RS485)

6. PWM3 for supply EC fan, PWM4 for exhaust EC fan

7. Inlet temperature sensor

8. Outlet temperature sensor

9. Supply air temperature sensor

10. Exhaust air temperature sensor

Functions and Features:

👷 Supported components:

2 fan motors: EC (PWM) or AC

Automatic or manual bypass (heat recovery switch)

Operating Modes:

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%.

Advanced Configuration Options:

🌐 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

Integration and Communication:

📡 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.
