Ventmatika EKA - Heaters EKA with Integrated Controller; Technical Characteristics of Controller EKR-KN

ELECTRICAL CIRCULAR DUCT HEATERS
EKA
11
Heaters EKA with integrated temperature controller EKR-KN… (See Fig. 11) can be controlled in
five different ways depending on control type:
Type EKA NV – potentiometer on the top of the heater casing for temperature control
Type EKA NI – external wired remote setpoint knob (TR5K) for temperature control
Type EKA NIS – external wired remote 0…10V signal for temperature control
Type EKA ESKM – external wired remote PWM (ON/OFF: ON(6…24)VDC) signal for temp. control
Type EKA MB – external wired remote temperature control via Modbus RTU protocol (RS485)
Electrical duct heaters EKA with integrated temperature controller EKR-KN… works by PID
regulator. That enable fine temperature control. Controller EKR-KN… controls load by Triacs without
moving parts, which causes no-noise commutation.
