MANIFOLDS AND ACCESSORIES Thermostat control panel VT.AC709

Electrothermal Servo Drive Valtec Normally Open 220V (VT.TE3040) for automatic control of radiator or collector thermostatic valves of water heating floor systems and cooling buildings based on signals from thermostats, sensors or controllers. This action is based on the expansion of the reinforced paraffin that fills the bellows when current flows through the built-in heating element. Normally open. Connection of servo motor to valve - via adapter (included).

The heat carrier temperature is controlled by applying a control signal to the actuator of the thermostatic valve of the mixing unit. The value of the control signal depends on the readings of the outside air temperature and coolant temperature sensors included in the controller delivery kit. The controller of the mixing unit VT.K200.M is suitable for the pump mixing unit VT.COMBI.S with the analog servo drive VT.TE 3061. The factory setting of the temperature curve (-20/+50° С; +15/+35 C) allows you to maintain a fairly comfortable temperature in any room with floor heating of any design and in any climate. If other temperature conditions need to be set according to thermal calculation, the user can set the temperature curve by himself. No additional controller setup is required.

The VT.ZC6 zone communicator is used to transmit the control signal (on/off) from the room thermostat to the actuator of the thermostatic valve, which controls the supply of coolant through the heating circuit. The use of a communicator simplifies the control scheme, allowing you to group thermostats and servo drives (group servo drives are turned on by a signal from one thermostat).

Additionally, the communicator has a relay output to control the circulation pump. If there is no heating demand in the room, turn off the pump. This saves energy and extends the life of the pump. Compatible with thermostats VT.AC609, VT.AC701, VT.AC710 without installing additional equipment, and servo drives VT.TE3041.0.024

Wall-mounted room thermostat with remote and built-in temperature sensor. Maintain the air temperature of a room or heated surface through two-position controls of the climate system equipment (mainly floor heating). External sensors are limited in the case of simultaneous activation of sensors. The user sets the value of the adjustable parameter through the setting wheel. The thermostat is equipped with an on/off key; device status is indicated by LED indicators. The thermostat is installed in a standard concealed junction box.
