KRC-PLUS

Product catalog summary
Overview: The KRC-PLUS is a radio-controlled advanced zoning system designed for individualized temperature control across different zones using the same air treatment equipment. It enhances comfort by allowing separate control of each zone and is compatible with duct-type direct expansion air handling units and optionally with uni-zone or multi-zone heating systems, including radiators or underfloor heating.
Key Features:
  • Modular zoning kit for independent temperature control in direct-expansion ducted air conditioning systems.
  • Optional heating module (/MH/) for controlling radiator or underfloor heating in 2 to 8 zones.
  • Incorporates MODBUS protocol for intelligent-building applications.
  • Controls up to 16 separate air conditioning zones and 8 heating zones with the addition of module /ME/.
  • Full control over mechanical air conditioning systems with the ability to override the air conditioner’s controller.
  • ON/OFF control for electronic air conditioning systems while retaining the original controller.
  • Enables Controlled Mechanical Ventilation (CMV) activation from the master thermostat.
  • Radio-controlled digital master chrono-thermostat with weekly programming.
  • Time-set radio-controlled zone thermostats with 30-minute interval timing.
  • Coded radio-controlled transmission system with over 3000 combinations.
Technical Specifications:
  • Heating Module MH: 8 potential-free relays 230 VAC x 10 A.
  • Zone-Damper Control: 3 potential-free relays 230 VAC x 10 A.
  • Control Board (Receiver): Power supply 230 VAC ± 10%, 50/60 Hz, consumption 10 VA, 6 outputs potential-free relays 230 VAC x 10 A for controlling air conditioning equipment, sixteen 24 VDC outputs for zone control, digital input for remote ON/OFF, protection class IP 20.
  • Thermostats (Emitter): Power supply 2 x 1.5 V LR06 AA, average operating life 1 year, temperature differential ± 0.5 ºC, protection class IP 20, carrier frequency 433.92 MHz, average range 50 m in free field.
  • Accessories: Motorised dampers (24 VDC) for mounting in MADEL grilles, circular ducts, and rectangular ducts, adjustable overpressure dampers (ZS series).
Environmental and Economic Benefits: The system promotes ecological friendliness by ensuring a rational use of energy, benefiting both economically and environmentally.

KRC-PLUS-1

KRC-PLUS radio controlled advanced zoning system Zoning System R/C allows for individualised temperature control of different zones using the same air treatment equipment to provide increased comfort in each one. KRC-PLUS control panel is compatible with any duct-type direct expansion air handling unit, and optionally with uni-zone or multi-zone heating systems, even radiators or underfloor heating. The control is carried out by means of digital thermostats linked by radio frequency to a control panel who operates the different motorised (24 Vdc) zone dampers. R/C Radio-controlled digital thermostats offer an easy installation: Neither thermostat wiring nor additional works are required. Ecologically friendly: Zoning System R/C provides a rational use of energy, both from an economic and environmental point of view.
