The California Title 24 Building Energy Efficiency Standards are designed to ensure new and existing buildings achieve energy efficiency and preserve outdoor and indoor environmental quality. We have included below useful information regarding underfloor heating and Title 24. To ensure compliance, please consult with a building professional.
Warmup strongly recommends that the relay is installed in a separate single gang box to avoid overheating and interference of other cables. Check with your electrician and refer to your local code for specific installation requirements.
Thermostats with an internal GFCI including the Warmup 4iE and WUDG will fulfill this requirement. If a non-GFCI thermostat like our Tempo thermostat is being used, a GFCI breaker will be required. Consult with your local electrician to make sure your installation is properly protected and meets National and Local Electrical Code.
