Changes in the range of automation

Dear Colleagues! We would like to inform you that VT.K200M weather-dependent controller has been cancelled from the VALTEC range starting from January, 2021. This position has been replaced by VT.K300 universal controller for mixer units.

The controller is designed for smooth regulation of heat carrier temperature in heating systems. The main sphere of application is control of one pumping and mixing unit of VT.COMBI, VT.TECHOMIX, VT.VALMIX types, as well as of quick installation module of VT.VAR20 or VT.VAR.21 types.

The device has two types of control outputs at the same time:
• for control of two-way valves of mixer units with electrothermal servo drive of VT.TE3041.0.024 or VT.TE3043.0.024 type: control is carried out by means of a PWM signal;
• for control of any rotary motor drives (VT.M106.0.230 or VT.M106.0.024) by means of two electromagnetic relays.

Besides valve control, the universal controller for mixer units makes possible pump control at the preset temperature.

The delivery set includes three digital temperature sensors allowing organization of one of control algorithms:
• by hear carrier temperature;
• by weather-dependent chart;
• by room air temperature;
• by room air temperature with limitation of the maximum temperature according to the weather-dependent chart.

The controller is powered from a 24 V constant voltage power supply unit. The power supply unit is included into the delivery set.
