CTC Pool Charging TBH Expansion Card

Description

Heat the pool efficiently with your heat pump and control a third separate heating circuit in the house in a convenient way. This expansion card (TBH / Accessory) expands the control capacity of the CTC EcoZenith i550 Pro multi-tank and gives you full control over more advanced heating systems directly via the heat pump display.

Included parts

• 1 pc Expansion circuit board (TBH): Mounted in the electrical compartment of the CTC EcoZenith i550 to communicate with the existing control board.
• 1 pc Room sensor: Ensures precise temperature control in the zone controlled by the third sub-shunt.
• 2 x System sensors (NTC): For reliable measurement of supply temperature, return or pool circuit temperature.
• Terminal blocks and installation instructions.

Functions and Areas of Application

Smart Pool Charging

By connecting the expansion card, your CTC EcoZenith i550 can automatically prioritize and control the heat supply to an external pool heat exchanger. The system reads the pool temperature via the system sensor and controls the charge pump and switching between the house's heat demand and pool heating.

Control of 3rd Subshunt (Extra heating circuit)

The property has several zones with different temperature requirements - for example, a combination of radiators on the upper floor, underfloor heating on the ground floor and a separate shunt group for the garage, conservatory or utility room.

• The expansion card enables control of heating system 3.
• The included room sensor and system sensors ensure that the shunt regulates exactly according to the set heating curve and indoor temperature.

Advantages of original CTC parts

• Seamless integration: All settings are made directly in the CTC EcoZenith i550's user-friendly touch screen.
• Optimized energy efficiency: The heat pump only produces the temperature that the pool or third zone actually requires, which minimizes energy losses.
• Operational reliability: All components are factory-calibrated to interact flawlessly with CTC's control system.
