1 Use and function
The TempTronic RC is a programmable control system for
TopVent ® gas units. A maximum of 8 units can be connected
to 1 controller.
Fig. G1: Room temperature controller TempTronic RC
Function
The TempTronic RC is connected to the units via a system
bus and fulfils the following functions:
■ Recording the room temperature with the integrated
temperature sensor
■ Regulation of the room temperature
■ Control of air distribution by means of the Hoval
Air-Injector
■ 3 set point values can be set (Room temperature
day, Room temperature night and Frost protection
temperature)
■ Control of operating modes according to week programme
and calendar
■ Registration of unit malfunctions in an alarm list
■ Password protection for user and service personnel
■ Menu-guided operation via a 4-line display
Location
Install the room temperature controller with the integrated
temperature sensor at a height of about 1.5 m at a represent -
ative location in the occupied area. Its measured values must
not be distorted by the presence of sources of heat or cold
(machines, windows, sunlight, etc.).
2 Regulation of the room temperature
TempTronic RC controls up to 8 TopVent ® gas units in
accordance with heating requirements. In fresh air operating
mode the units are constantly in operation; the fresh air ratio
for supply air units can be regulated (0 – 100 %). In recircu -
lation mode the system operates in the energy-saving on/off
mode. The fuzzy-logic-based regulating algorithm switches
the units according to criteria different from those of conven -
tional 2-point regulators; the deviations are thus smaller.
The TempTronic RC system comprises an automatic frost
protection switching function:
■ If the room temperature drops below frost protection
temperature, the units are switched on.
■ Once the temperature has risen by 2 °C the units switch
off again.
The frost protection temperature can be regulated.
3 Control of the air distribution
The patented air distributor – the so-called Air-Injector –
delivers varying volumes of supply air at different tempera -
tures draught-free to the occupied area of high spaces. This
is made possible by the vortex device, by means of which
the blow-out direction of the air can be adjusted infinitely
variably from vertical to horizontal. It depends on:
■ the mounting height
■ the air flow rate (→ fan speed)
■ the temperature difference between supply air and room air
In certain cases the Air-Injector can be set to a fixed value
when commissioning takes place. For the TempTronic RC
to automatically adapt the delivery direction of the air to
changing operating conditions, an Air-Injector actuator is
required.
