A hydronic floor heating system as it relates to an HVAC apparatus, approach and system. Aspects of the present system and approach may include a radiant floor optimization mode, low floor temperature in vacation mode, modifying a 300 Hz, or so, reading principle base on implementation of Pseudo-random jittering of a reading event improving short-term accuracy of the individual readings, and a combination of hardware and software filters for using thermal sensors with extended cable length.

Hydronic floor heating systems with features

A motion detector having a bandpass filter is described herein. One device includes a passive infrared (PIR) sensor configured to generate a signal, and a bandpass filter configured to filter the signal, wherein the bandpass filter comprises a plurality of high pass filters, a plurality of low pass filters, and two operational amplifiers, wherein a portion of the plurality of high pass filters include a capacitor and two resistors.
