Direct heating convection heaters are typically able to react to heating requirements very rapidly, and are therefore also suitable e.g. for buildings which are used occasionally and irregularly.
Direct-heating convection heaters
Direct-heating convection heaters

A standard type of convection heater, fitted with an accurate electronic thermostat (accurate to 0.1°C) with a pilot wire. The convection heater consists of a body fabricated from steel sheeting, a control unit and a lamella heating element. The surface of the convector is coated with white comaxite, including the grille. The heater is to be attached firmly to the wall (the mounting frame comes with the product) with its power supply lead connected to a wiring box.

BMR HC64 A control unit for the HC 64 system with a WEB interface, TCP, and USB connectivity. Power supply 24 VDC / 2.5 A; control software for PC, USB cable.
The control unit is designed to be used to control warm-water systems (in combination with other components). If connected to HTS64DIN_R modules, it can also be used to control electric heaters that are fitted with a pilot wire. One HC64SZ control unit can control up to 32 HTS64-DIN_R modules (32 zones).
BMR HTS 64-DIN_R If a building is heated by heaters (convection heaters) fitted with a pilot wire, their operation can be controlled by signals sent via the pilot wires using a BMR HC64SZ control unit and BMR HTS64-DIN_R modules.
Convection heaters with a pilot wire have a built-in thermostat with which the user sets the comfort temperature they require in a given room. As soon as the heater receives a signal via the pilot wire, it automatically (without any action being required from the user) starts to maintain the attenuation (lowered) temperature in the room. This is usually 4°C lower than the comfort temperature. A subsequent signal acquired via the pilot wire will return the heater back to the comfort temperature. Each signal arriving via the pilot wire switches the heater between these two temperatures.
The signals themselves are sent by the HTS64-DIN_R module, which must be subordinate to the HC64SZ control unit, whose 1-week programme sets when the room should be heated to either the comfort or the attenuation temperature. If there are more rooms in the building which should have different “comfort/attenuation” time modes (a new zone), another HTS64-DIN_R must be installed. The building can thus be divided into individual zones with their own 1-week programmes as needed. One HC64SZ control unit can control up to 32 HTS64-DIN_R (32 zones).
