Premium series

Electric boilers of the Premium series by Tenko have two lines – Premium (boilers with capacity from 3 kW to 15 kW), and Premium Plus (boilers with capacity from 3 kW to 36 kW), that provide wide opportunities for controlling the device work and provide the maximum comfort and autonomy of operation at heating of various premises with the maximum area to 360 sq.m., are produced with capacity from 6 to 36 kWand may be connected to a 220V network (capacities of 6kW, 9kW and 12kW) and 380V (all others). The available series stand out by the built-in microcontroller and the software control system for full control of working capacity of a boiler which is automatically updated. Premium boiler models have a digital display for setting and displaying service information from three temperature sensors:  room (wired or radio temperature control from 7 to 40C) (wired temperature sensor comes complete with the boiler with the installation being mandatory for correct operation boiler, or it can be blocked in the menu Service-section Locking for boiler operation only on the coolant, but MMT modes (maintenance of minimum temperature), modulation, timer and pauses on/off the circulation pump), sensors on the direct and return pipelines of heating systems (temperature control from 10 to 75C will not work). The microcontroller controls the heat exchanger blocks and relays, and the built-in software electricity meter keeps statistics and allows optimizing the work. Silent operation during switching is provided by solid-state relays with water cooling. Operation of boilers is possible only in the closed heating system (there is no exit of the coolant outside). The boiler has three power levels and functions such as smooth start (smooth connection of heating elements when starting the boiler from the minimum value to the set one), power modulation (when activating this function the boiler programmatically chooses how many power levels to turn on in the given cycle of work), selectivity of the heating element (at the included function of modulation each new cycle the boiler in turn switches on various heating elements that gives the chance to increase a resource of their work), MMT function (maintenance of the minimum temperature – in long absence temperature may be set at  7-17C degrees, which the boiler will support when activating this function), diagnostics of power channels (with error notification), antifreeze function (every 60 minutes the circulation pump is switched on for 1 minute when the boiler is in sleep mode: if the coolant temperature is less 5C the heating is switched on, the pump works for another minute after switching off the heating). All models of Premium electric boilers by Tenko have a circulating pump by Grundfos (Denmark) (UPSO 15/60-130), a Zilmet expansion tank (Italy) with a capacity of 7 liters (only Premium Plus series), a pressure sensor, an automatic air vent and a safety valve made in Italy, a daily/weekly program module allowing controlling the boiler remotely. Remote control of the boiler is carried out through any browser or Android/IOS application.
