Solution - Water Heater
Description
Water heaters can be integrated into the PIERRE system using a relay output, enabling automated and remote control of the device. This allows users to manage water heating schedules, improve energy efficiency, and ensure hot water is available when needed.
Relay Selection
Water heaters are typically high-power electrical loads and may draw significant current during operation. When connecting a water heater to the PIERRE system, it is essential to use a relay, contactor, or switching device that is correctly rated for the electrical characteristics of the heater.
For larger installations, a dedicated contactor controlled by a PIERRE relay output may be required.
Automation
Water heaters can be included in automations, schedules, and scenarios. Common use cases include:
- Time-based operation schedules.
- Off-peak energy management.
- Automatic shutdown when the building is unoccupied.
- Integration with energy management strategies.
- Operation based on system events or other device states.
Remote Control
Users can monitor and control the water heater remotely through the PIERRE application. This allows the heater to be switched on or off from anywhere with internet access.
Energy Management
Automated control can help reduce unnecessary energy consumption by ensuring the water heater operates only when required. Scheduled operation and occupancy-based control can contribute to improved energy efficiency and reduced operating costs.

FAQ
Yes, an illuminated push button can be used for water heater control. The indicator light can be connected to the Controller output, allowing the push button to visually indicate when the water heater is operating. The indicator must be compatible with 12V DC, which is the recommended solution. If a higher-voltage indicator is used (such as 24V AC/DC or 230V AC), an additional relay or interface device may be required. Always verify the voltage and current requirements of the indicator before connecting it to the system.
