Page 4: Safety Requirements
Safety requirements All installation and wiring work on the controller must only be carried out in a zero volt state. The opening, connection and commissioning of the device may only be carried out by competent personnel. While doing so, they must observe all lo- cal safety requirements. -
Page 5: Maintenance
Maintenance If treated and used correctly, the device itself will not require any maintenance. However, the use of a suitable sacrificial anode in the cylinder is recommended, and if the immersion heater is used more often than usual, it is necessary to check whether the material thickness is reduced (at least 2-3 times per year). -
Page 6: Function Description
Funktionsbeschreibung Function description The EHS immersion heater is available in two versions: • EHS-R: With variable control from 50 W - 3000 W • EHS: Output 0-3000 W in 750 W increments Combining an EHS-R (controllable) with one or multiple EHS (not controllable) enables a cascade to be set up in which the EHS-R carries out fine adjustment, achieving stepless power regulation. -
Page 7: Installation And Connection
Installation and connection Installation and connection With regard to the material, the immersion heater is suitable for installation in DHW cylinders, but due to the predominant electroplating in the cylinder, less no- ble metals than those of the immersion heater are damaged. The use of a suitable sacrificial anode in the cylinder and regular checking of the anode (at least 2-3 times per year) is recommended. -
Page 8: High Limit Safety Cut-Out (Hlsc)
Installation and connection High limit safety cut-out (HLSC) The EHS-R has a sensor for the high limit safety cut-out. This is a PT1000 sensor in a sensor well between the heating elements. It is connected at the factory at the connection shown below. When a temperature of 95 °C is reached at the STB sensor, the immersion heater is deactivated. -

Installation and connection Mains connection Phase Neutral conductor Earth conductor Heating elements The 3 heating elements are connected at the factory and fully wired. For any installation/mainte- nance work, ensure correct wiring/connection. The EHS-R has 3 heating elements: • 750 W controllable •... -
Page 10: Wireless System
Wireless system Wireless system Principles The wireless system comprises at least two devices (e.g. CAN-EZ3 and EHS-R), which communicate with one another, exchange data or send firmware/function data. The wireless range is around 1000 m outdoors, and typically 30 m in buildings (through approx. 2 walls/ceilings, depending on thickness and material). -
Page 11: Relaying Wireless Signals
Wireless system Relaying wireless signals Wireless-capable devices can relay signals of other devices. All required settings for this are carried out at the device, which transmits the signal to be relayed. The EHS-R can be used to relay wireless signals. If the EHS-R immersion heater receives signals via a relay, it automatically returns data via the same relay. -
