Introduction

The ECB62ZB control box is the core component of the underfloor heating control system. It is equipped with 230V voltage connectors for thermostats, pumps, and thermoelectric actuators, enabling control of up to 8 heating zones (2 wired, 6 wireless). It is compatible with NC-type thermoelectric actuators (e.g., E30NC230, E28NC230) and features a built-in control module for heating devices, such as a gas boiler, via a voltage-free output. Wired control involves direct connection of thermostats, which can be battery-powered or 230V AC powered. Wireless communication is facilitated by ⚡️ ZigBee 3.0 technology. The "ENGO binding" function allows direct wireless control of dedicated EONEBAT and EONE230 thermostats using the EGATEZB internet gateway. The EGATEZB gateway also enables remote control of the ECB62ZB via the ENGO Smart/TUYA Smart mobile applications over the internet.

Product Compliance

This product complies with the essential requirements and other relevant provisions of the following EU Directives:

• EMC 2014/30/EU
• Low Voltage Directive LVD 2014/35/EU
• ROHS directive 2011/65/EU

Safety Information

Use in accordance with national and EU regulations. The device is intended for indoor use only in dry conditions. Installation must be carried out by a qualified person in accordance with national and EU regulations. Before attempting setup and installation, ensure the ECB62ZB is not connected to any power source. Incorrect installation may cause damage to the wiring center. The ECB62ZB should not be installed in areas exposed to water or damp conditions. The installer is responsible for ensuring all additional protection requirements are met.

Connection of Thermostats and Thermoelectric Actuators (AC 230V)

The system supports various thermostat types for connection:

• Wi-Fi Thermostat (e.g., E10)
• Wired Battery Thermostat (e.g., EASY/E901)
• ⚡️ ZigBee Thermostat (e.g., EONE)

The ECB62ZB control box connects to:

• Wired zones labeled "A" or "B".
• Wireless zones 1-6, typically via a ⚡️ ZigBee connection, potentially through an EGATEZB Gateway.
• Pump output (AC 230V).
• Boiler output, which uses voltage-free contacts (NO/COM/NC).

Thermoelectric actuators (e.g., E30NC230) connect to the actuator output terminals. Each zone is designed to support up to 6 thermoelectric actuators (2W each). If more actuators are needed per zone, an additional relay must be used to relieve the output. The control box is designed for NC (normally closed) type actuators, meaning they are closed when unpowered and open when powered. 230V AC may appear on the actuator outputs depending on the thermostat's heating state.

Installation

Follow these steps for installation:

1. Remove Top Cover: Carefully remove the top cover of the control box. A gap of approximately 5mm is needed to facilitate this.
2. Wire Preparation:
   • For boiler and battery thermostats: Use wires with a minimum of 2 x 0.75 mm² and a maximum of 2 x 1.5 mm² (230V).
   • For power supply, pump, and 230V thermostats: Use wires with a minimum of 3 x 1.0 mm² and a maximum of 3 x 1.5 mm² (230V).
   Strip approximately 40mm of insulation from the ends of the wires.
3. Connect Wires: Connect all wires according to the connection diagram and the instructions provided on the sticker inside the top cover. Ensure correct connections for the power supply, pump, boiler, and actuators.
4. Finalize Installation: Securely re-mount the top cover. Connect the wiring center to the 230V power supply. The red "Power" LED indicator should illuminate, confirming power connection.

Power Supply and Fuse

The control box requires a stable 230V AC 50Hz power supply. The installation must adhere to a three-wire system and comply with all applicable regulations. The illumination of the red "Power" LED signifies that the wiring center is successfully connected to the power supply.

Fuse Replacement: The main fuse, a 10A slow-blow tubular type, is located beneath the housing cover, adjacent to the power supply terminals. It protects both the control box and connected devices. Fuse replacement should only be performed when the control box is disconnected from the power supply. Use a flat screwdriver to carefully remove the fuse holder and then extract the fuse.

Pump Control Output (AC 230V)

The PUMP OUTPUT is utilized to power the circulation pump within the heating system. It is a 230V AC voltage output with a maximum load capacity of 3A. The pump is connected directly to these terminals. The output activates (and the pump starts) exactly 3 minutes after receiving a heating signal from any thermostat connected to the wiring center. The output deactivates (and the pump stops) as soon as the last thermostat ceases to report a heat demand. When the Pump/Valve control output is activated, the pump status LED displays a constant green light.

Boiler Control Output (Volt-Free)

The boiler control output is managed by a relay featuring voltage-free contacts (NO / COM / NC output). The boiler must be connected to either the COM-NO or COM-NC contacts. This is a standard two-state relay. If thermostats connected to the wiring center send a signal requesting heat, the BOILER output contacts activate the relay with a 3-minute delay, initiating the boiler's operation. The boiler is turned off immediately once none of the zones are requesting heat. When the BOILER control output is activated, the boiler status LED displays a constant green light.

Note: The shutdown delay time for both the circulating pump output and the heat source output can be adjusted within a range of 0, 3, 5, or 15 minutes. Refer to the full device manual for detailed configuration instructions.
