1. Description of controller. The GH07EB controller is a device used to control water heating installations using electrode furnaces. The GH07EB controller is a microprocessor-based device manufactured using Surface Mount Technology (SMT). This controller controls the domestic hot water (DHW circuit), and provides support for the main heating circuit (CO). -

Schematic diagram for controller installation: ONLY A QUALIFIED WIRING TECHNICIAN MAY CONNECT DEVICES TO THE GH07EB CONTROLLER 5. Controller modes This controller can operate in four modes: • Standby – the controller returns to the state it was in before the loss of power supply. The control algorithm is not implemented, and the previous settings and chosen installation are stored. -
Page 7: Standby Mode
5.1. Standby mode. After installation as described in the previous chapter, the GH07EB controller goes into standy mode. In this mode the screen displays four lit dashes. When the controller is in standby mode, it is possible to go to manual mode using button . -
Page 8: Manual Mode
5.3. Manual mode. In manual mode, the controller does not activate the algorithm, and the number and type of attached devices are dependent on the user, who takes responsibility for the correct operation of the equipment. The system temperature is displayed on the main screen. On entering manual mode, all connected devices are stopped automatically. -

The hot water pump is only accessible if it has been selected for use in the service parameters ( Ch.13, P.21) ⇒ When in manual mode the controller can work for a limited time with the electrode boiler and pump turned off, to protect against the risk of boiler temperature rising. -
Page 12: Description Of Additional Functions
7. Description of additional functions 7.1. DHW priority The GH07EB controller allows DHW to be set as priority mode. In this mode of operation, heating hot water becomes priority and CH takes a secondary position. This is available only in the second heating configuration. To enable, set the value „1” in user parameter U8. - Page 13 - Signals that the anti-legionella function is active. This function is available only in the second heating configuration. The anti-legionella function takes priority over all others, meaning that it is performed by the controller first. When this function is enabled, the temperature of the water in the boiler is raised to 70°C and this temperature is maintained for ten minutes.

10. Temperature limiter (STB). An additional independent temperature limiter (STB) can be connected to the GH07EB controller, via terminals 15-16 (⇒ p.6). This provides additional mechanical protection against excessive temperature rises in the heating system. If the temperature limiter disconnects the contacts due to rising temperature from the boiler, disconnect the electrode boiler from the power supply. -
Page 18: Power Failure
Correct connection with the controller is signalled by a lit LED behind icon on the GA01HC room panel If the GH07EB electrode boiler controller is connected to the GA01HC-01 room panel, this will be detected automatically by the controller and activation does not require any additional steps or settings from the user. -

It is possible to connect an external thermostat to the GH07EB controller (⇒ p.6), which, when activated, will close output contacts and lock the boiler. The room thermostat can lock the boiler by overriding the driver input that supports the thermostat (when the thermostat is active). - Page 20 P.P.U.H. „Geco” Sp. z o. o. 32-060 Liszki, Polska Cholerzyn 376 tel. 012 6369811, 6361290 fax. 012 6362002 http://www.geco.pl...
