SRT BACnet and Modbus Touchscreen Room Thermostats - Slimline State-of-the-Art Look Packed with Features!

SyxthSense is pleased to introduce our new touchscreen range of room thermostats. The SRT thermostats are suitable for wide variety of applications and have intuitive 3.5” touchsreen for viewing the system status and modifying the settings. The 320x480 pixel 255K colour touchscreen provides a dynamic sharp graphical interface to the heating and cooling control.

The thermostats can operate as stand-alone switching directly boilers and plants via built-in 7A 230Vac rated relay. Alternatively the BACnet and Modbus models can be used as a network thermostat for home and building automation systems. In system applications the thermostat can also be used to switch the Lighting and/or Air-Conditioning on/off. As the modern buildings, houses and apartments require ever more comfort features to SRT Touchscreen thermostats can act as an important part of the system providing attractive interface to the control.

The SRT BACnet touchscreen thermostats and Modbus thermostats thermostats can be a companion for building automation and home automation systems. The industry standard BACnet and Modbus protocols guarantee interoperability to most home automation systems such as Crestron and Control4, as well as building automation and control systems such as Trend, Tridium, Honeywell, Alerton, Priva and SyxthSense Sedona solutions. Connecting SRT BACnet and Modbus thermostats to these systems release the full potential of the attractive user interface with system functionality.

The SRT touchscreen thermostats are equally suitable for stand-alone installations where the thermostat is used to replace the existing "non-intelligent" thermostats such basic Honeywell, Sunvic, Drayton and Sunvic models. Using the SRT touchscreen range the system is upgraded for a state-of-the art interface with many energy saving features. The energy saving features include Cleaning Mode where the system is switched of for a timed period. This can be activated via e.g. window contact or manually from the thermostat. In system installations the cleaning mode can also be activated automatically over the BACnet or Modbus network.

The non-programmable SRT touchscreen thermostats feature an ECO mode, that allows the temperature to operate under reduced setpoint (heating mode) or increased setpoint (cooling mode) to reduce the energy consumption automatically during the unoccupied/night periods. The mode can be automatically activated over the BACnet or Modbus communication network.

The SRT touchscreen thermostats have built-in holiday mode. Upon the activation of the holiday mode, the thermostats is switched to a reduced setpoint for a specified period. The holiday mode can also be activated over the BACnet or Modbus interface.

The SRT touchscreen thermostats have also range of comfort features to guarantee the optimal conditions in the room space. The built-in Boost button switches the system on for a specified period, allowing the heating to be switched on e.g. on arrival to the space. The SRT touchscreen thermostats feature a remote sensor input for underfloor heating minimum and maximum control. When the floor tmeperature exceeds a set temperature the thermostat switches the relay output off protecting the floor surface. If the floor temperature drops below a minimum setting in the heating mode, the heating is forced automatically on. This allows the SRT thermostats to be used e.g. in bathrooms where the floor temperature is kept at the level comfortable for bare feet. In the cooling mode the minimum temperature can switch off the relay i.e. protect the system from condensation.

The built-in frost protection is always active offering building fabric protection during the off or holiday periods.

LANDLORD THERMOSTAT MODES

The SRT Touchscreen BACnet and Modbus thermostats are also suitable for Landlords. The thermostats have programmable 4-digit LOCK code and 4-digit MAINTENANCE CODE for accessing the configuration settings. For examples it is possible to limit the user temperature adjustment limits, or LOCK the thermostats adjustment completely. The thermostats can be controlled over the Modbus or BACnet network from the system master device.
