Room Thermostat

4200-2831 room thermostat is used in air conditioning plants and it is especially suitable to residential applications, offices, hotels, etc.
Picture of BD297


The BD297 differential pressure switches are used in air conditioning and ventilation systems to control the differential pressure of filters, batteries and fans. They are electromechanical regulators of the two position type with silver contacts and two 6 mm diameter pressure fittings for PVC flexible pipe (pressure coupling). The differential trigger pressure can be varied from the knob on the front of the device from 40 Pa to 400 Pa. The BD297 is equipped with a 1.5 A relay (0.4 A inductive) at 250 Vac and has a degree of protection IP54.
Picture of TQ-D32-CO2


The TQ-D32 air quality transmitters are designed to control fresh air flow in air conditioning systems. Two different models are available. TQ-D32-CO2 determines the air quality through measurement of CO2 concentration (ppm). The output signal can be used to control fresh air fans and dampers according to the ventilation load. It is equipped with a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about.
Picture of Y111RM


The thermostats of the Y111 series are used for the antifreeze protection of both batteries and water pipes. Both models of the series have a capillary able to detect the minimum temperature on the battery or on the surface of the duct. They are available both in the version with automatic reset (Y111) and with manual reset (Y111RM). Both models are equipped with a 6 m long capillary. For correct operation, the thermostat must not be placed in an area with a temperature lower than that of the capillary. The thermostat casing guarantees a degree of protection IP43.
Picture of TP-D334


The TP differential pressure transmitters are used in air conditioning system for the measurement of differential pressure in the environment or in the air duct and in hydraulic distribution system, civil and industrial. The transmitters detect the pressure value to be measured by means of a sensitive element whose movement is linearized and transformed into an output signal.
Picture of Y106


The flow switch Y106 finds application in the control and monitoring of water flow in pipes with diameters from 1" to 8" in heating, cooling and air conditioning systems in general. It is calibrated at the factory at the intervention value indicated in the technical documentation supplied with it. The product is supplied with 4 pallets of different sizes to allow a calibration of the intervention threshold. The water flow switch can be mounted on short or T-shaped connections. The electrical contacts are of the SPDT type with a capacity of 15A at 230 Vac . The casing has a degree of protection IP65.
