Page 3: 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 4: 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 5: Introduction
Introduction Introduction The ATON set comprises a CAN-EZ3A energy meter and a variable EHS-R immersion heater. These two devices communicate wirelessly with one another. The energy meter and immersion heat- er are connected at the factory. This means that no wireless connection settings are required. How- ever, information can be found in chapter Wireless system. -
Page 6: Factory Settings
Factory settings Factory settings The CAN-EZ3A is programmed at the factory and this programming is described in more detail in the following pages. This programming can, of course, be changed or replaced with your own program- ming. The energy meter can be fully programmed via the display and control buttons/rotary dial, but we recommend using the PC software TAPPS2 for this. -
Page 7: Functions
Factory settings Functions A more detailed description of all function modules can be found in the corresponding operating instructions for freely programmable controllers (www.ta.co.at). The primary functionality comprises the Output control of the EHS-R immersion heater and an Ener- gy manager, in connection with a Comparison function. •... -

Factory settings Datalogging The following values are logged at the factory: • EHS-R Temperature 1 (sensor input S1 of the immersion heater) • EHS-R Current output in kW • CAN-EZ3A Electrical power (total real power) • Function Energy meter (kWh total) Datalogging on SD card is deactivated at the factory. -
Page 9: Installation And Connection - Can-Ez3A Energy Meter
Installation and connection Installation and connection – CAN-EZ3A energy meter The CAN-EZ3A is installed in a meter box in accordance with local regulations. It can be snapped on to a top-hat rail (DIN support rail TS35 to EN 50022). The 2-pole connectors of the current transformers are connected to the CAN-EZ3A and folded over the cores. -

Installation and connection 3-phase measuring All 3 phase conductors (L1 - L3) are connected to voltage terminals L1-L3 and the neutral conductor to the N terminal. The 3 external hinged current transformers are connected to terminals I1 – I3 in the correct sequence and folded over the wires to be measured. -
Page 12: Installation And Connection - Ehs-R Immersion Heater
Installation and connection Installation and connection – EHS-R immersion heater 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 13: 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. -

Page 15: Wireless System (Cora)
Wireless system (CORA) Wireless system (CORA) Principles The wireless system comprises multiple CORA devices (e.g. CAN-EZ3A and EHS-R), which commu- nicate with one another, exchange data or transfer firmware. This functionality cannot fully replace the CAN bus. For the wireless system, the CAN-EZ3A has an external antenna. The wireless range is around 1000 m outdoors, and typically 30 m in buildings (through approx. -
Page 16: Relaying Wireless Signals
Wireless system (CORA) Relaying wireless signals CORA devices can relay signals from other devices. All required settings for this are carried out at the device, which transmits the signal to be relayed. Pairing with devices that simply relay signals is not required. -
Page 17: Control Via Pwm - Without Wireless Connection
PWM control Control via PWM – without wireless connection To operate the EHS-R without a wireless connection (e.g. in conjunction with controller UVR16x2 or CAN-EZ3 and output extension AO4-DL), the immersion heater has a PWM input. 10-90% PWM cor- responds to 0-3000 W output, but operation only starts at min. 45 W (equates to around 12% PWM). Important: If an active wireless connection is available (paired and signals being received), the PWM input is inactive. -
Page 18: Notes On Accuracy
Notes on accuracy / Reset / LED status indicators Notes on accuracy The accuracy of all measured energies and energy flows depends on many factors and is to be sub- ject to closer consideration here. • PT1000 class B temperature sensors have an accuracy of +/- 0.55 K (at 50 °C). •... -
