Frequently Asked Questions

Q1: What is the difference between water underfloor heating thermostats and electric heating thermostats?

A: Water underfloor heating thermostats typically control thermal actuators, motorized valves, or gas boilers, requiring a 3A relay load with potential-free or dry-contact outputs. In contrast, electric floor heating thermostats must handle direct heating mats and cables, requiring a heavy-duty 16A load capacity. E-TOP manufactures robust solutions for both application types.

Q2: Can E-TOP's water heating thermostats be integrated with multi-zone wiring centres?

A: Yes. Our water floor heating thermostats (including models like HT-70, HT-66, and our modular color touch series) are fully compatible with centralized HVAC Wiring Centres. This enables synchronized multi-room thermal management for residential and commercial underfloor systems.

Q3: Do you offer custom UI and protocol development for water heating projects?

A: Absolutely. Beyond standard Tuya WiFi or Zigbee options, we provide deep software and hardware ODM customization. To see how we streamline brand customization, check out our guide on custom TFT thermostat UI solutions.
