Product Overview

The SAS816WHL NonProgrammable Rotary Dial Hydronic Thermostat delivers simple, reliable temperature control for water underfloor heating. Its intuitive rotary dial eliminates any learning curve. A builtin DIP switch allows quick changeover between heating and cooling modes, simplifying onsite commissioning. The thermostat supports up to 8 independent zones when paired with a wiring center, and offers room, floor, or dualsensor modes to protect flooring materials. Antifreeze protection automatically activates heating when temperatures drop below 5℃, preventing pipe bursts. CE certified, factory direct, OEM/ODM ready.

Product Features

Easy Operation – Rotary dial design

Turn the dial to set the desired temperature – no complex menus, no programming. This intuitive interface reduces user errors and support calls, making it ideal for rental properties, senior housing, and budget-conscious projects.
Entry-Level Compliance – Meets basic requirements at lower cost

Designed to fulfill essential safety and functional standards for hydronic floor heating, this model offers a cost-effective solution without compromising reliability – perfect for large-scale housing developments and retrofit programs.
Simplified Commissioning – DIP switch for heating/cooling mode

A manual DIP switch instantly changes the operating mode between heating (for floor heating) and cooling (for fan coil systems). This eliminates complex menu navigation, speeding up installation for contractors.

Supports Multi-Zone Projects – 8-Zone Control with wiring center

When connected to a wiring center, the thermostat becomes part of an 8-zone independent heating system. Each zone can be controlled separately, delivering tailored comfort and reducing energy waste in larger properties.
Advanced Floor Safeguard – Intelligent Dual-Sensor Protection Modes

Supports internal room sensor, external floor sensor, or both. Strict floor temperature limits prevent warping of wood or cracking of tiles, dramatically lowering post-installation callback costs and protecting your investment.
Winter Reliability – Anti-freeze protection + pump-valve-boiler interlock

The automated anti-freeze function turns on heating when the room temperature falls below 5℃ and stops when it reaches 8℃. Built-in interlock logic ensures the boiler runs only when a zone calls for heat, protecting pipes in unattended properties.
