Hörmann HKSA humidity sensor, outdoor

The Hörmann HKSA measures air humidity and temperature outside the garage. It is connected to the HKSI-1 indoor sensor, which then controls garage ventilation by comparing the conditions inside and outside. If it is more humid outside than inside, the door does not open for ventilation. The HKSA does not work on its own without the HKSI-1.

How the two-sensor system works

• Setup – the HKSI-1 detects the connected HKSA and configures the system automatically.
• Dew point – on the HKSI-1 you set a dew point temperature deficit of 1 to 5 °C (factory setting 3 °C).
• Fan – an optional fan is connected via the HOR 1 relay to the second connection of the HKSI-1. It switches on when the door reaches the ventilation position.

Things to consider before installation

• Operator – only ProMatic 4 and SupraMatic 4.
• Location – protected from direct rain and sun, ideally on the north side of the garage, not on the windward side, away from an overhanging roof.
• Safety – if the bottom edge of the door is 30 mm or more above the floor in the ventilation position, a light barrier is required.

You can buy both sensors together as the HKSI-1 and HKSA set. Send questions to eshop@saver.sk.
