Ready-to-install convector-based trench convectors
Assembly and installation instructions
11.4 230 V electromechanical electrical model
Design for on-site control or for room regulation with intuitive operation of the
Ka
therm
QK.
Product features
The
Ka
therm
QK features an integral switch power supply to connect to the 230
V AC voltage supply.
• In the event of a motor fault, the fan automatically switches off and a fault
signal is issued at the potential-free contact.
The required room temperature is set on the room thermostat type 342924. If
this falls below the set value, the cross-flow fan starts up at the set speed and the
thermoelectric actuator valve opens the water-side valve.
If the speed controller is switched to zero (Off), only the water-side valve opens
(natural convection operation).
Room thermostat with continuously variable speed setting, in a flat surface-
mounted housing, white, with thermal feedback; for the continuously variable
parallel control of max. 10
Ka
therm
QK 230 V electromechanical models, room
temperature and fan presetting using dials; temperature setting range 5 - 30°C;
IP 30 rated,voltage 230 V/50 Hz, max. current load 4 A, switching difference 0.5 K,
temperature drop approx. 4 K, fuse and EMC in line with DIN EN 60730
Dimensions W x H x D: 78 X 83 x 27 mm
