The E-R is the simplest DITRA-HEAT thermostat — turn it on, set your temperature, and that's it. No schedule, no app, no WiFi. Perfect for a single bathroom where someone just wants a warm floor in the morning.

• Non-programmable digital thermostat with backlit display — works with 120V and 240V systems, built-in Class A GFCI
• Handles up to two heating cables or 15A total — floor sensor included with your heating cables, adjustable temperature range
• Fits a standard single-gang electrical box — installs in minutes, no network setup or app pairing required

Pro tip: If you pair this with a simple timer switch upstream, you get basic scheduling without paying for a programmable thermostat. But for most people, the E-RT's built-in schedule is worth the upgrade.
