The Siemens RDE 100.1 is one of the latest large-screen models.

Size: 127mm H x 85mm W x 21.5mm D for the thermostat. The screen is 70mm x 48mm.

The RDE thermostats offer easy 7-day programming at a very affordable price. On and off periods for each day of the week are individually programmable.

Temperature range 5-35 degrees Celsius.

The actual room temperature is measured via an in-built sensor, and On/off commands are sent to the heating system.

The thermostats are two-position controllers with a two-wire connection.

The thermostat does not come with floor probes but can support floor probes, which will cost an additional $20 each.
