Ontech

The device communicates with the main unit with a short-range radio frequency of 2.4 GHz. Up to 7 Ontech GSM Relay can be connected and controlled individually to each main unit.
The unit has a 230V outlet that can be switched on and off by any of the main devices such as elements, pumps, etc.. The power supply can be delayed, from 1 second to 99 hours.
The unit has a built-in temperature sensor. An external temperature sensor can be connected. This is an optional accessory and is not included. Upon request, the unit reports the temperature.

The unit can be set to alert if the temperature exceeds or falls below a preset temperature.
The unit can be used as a thermostat if one element is connected to the 230 V socket.
The device has two wired alarm inputs. These can be set to end up (Normally Open, NO) or Breaking Function (Normally Closed, NC). Various types of alarms can be connected to these, such as fire alarms, motion detectors, level detectors, etc.

Easy to install. Put the device into a wall outlet and it automatically contacts the main unit and registers in the Ontech system.
The range is approximately 30 meters in the free field. This is usually enough for a normal sized villa. The devices also function as “repeaters”, ie they forward the radio signal to the main unit from devices further away. This increases the range of the system.
