EKR 15.1
ACCESSORIES
Controller of electrical heating
EKR15.1 is a proportional controller for electric heaters with
automatic voltage adaptation. EKR15.1 controls the whole
load On-Off. The ratio between On-time and Off-time is varied 0-100% to suit the prevailing heat demand.
EKR15.1 is designed only for electric heating control. The control
principle makes it unsuitable for motor or lighting control.
EKR15.1 can control 15kW heater and has relay output for extra
load control with contactor, on which can be connected load up to
12kW. Full load can be 27kW.

EKR15.1 has zero phase-angle detection to prevent RFI (radio
frequency interference).
EKR15.1 automatically adapts its control mode to suit the dynamics
of the controlled object . For rapid temperature changes i. e. supply
air control EKR15.1 will act as a PID controller. For slow temperature
changes i.e. room control EKR15.1 will act as a PID controller.
Night set-back
Potential-free closure will give a night set-back of 0-10°C. Settable
with a potentiometer (Contacts 10, 11) in the EKR15.1.
* Extra load should be connected via contactor to the relay output.
Controllers conforms to requirements of standards EN 61010-1+A2:
2000, EN 50081-1: 1995, EN 55022: 2000 and carries CE mark.
