The EPH TS22 Smart 2-Zone Thermostat Pack (EMBERTS22) is a versatile multi-zone digital control system designed to deliver precise time and temperature management across two independent heating zones, or a heating zone and a domestic hot water cylinder. Supplied as a complete, pre-paired installation kit—featuring two wireless Touch Thermostats, a dual-channel RF receiver, a Wi-Fi gateway, and an included NTC10K temperature probe—it provides an all-in-one smart heating upgrade with remote management via the EMBER Smart Heating App.

The standout feature of the TS22 is its adaptable second thermostat, which can function as a secondary space heating controller or be configured into a smart cylinder thermostat using the included NTC10K sensor probe (also suitable for underfloor or adjacent room sensing). With native 7-day, 5/2-day, or 24-hour schedule programming, built-in Optimum Start, and TPI control algorithms, the TS22 delivers maximized energy efficiency and comfort for modern multi-zone heating and hot water systems.

Main product features:

• Dual-Zone Smart Control: Simultaneously manages two independent space heating zones, or one heating zone and a hot water cylinder.
• Includes NTC10K Temperature Probe: Converts the second thermostat into a cylinder thermostat, or measures floor/adjacent room temperatures with ease.
• Complete Pre-Paired Pack: Includes two wireless Touch Thermostats, a 2-channel receiver, and a GW04 Wi-Fi gateway pre-linked out of the box for quick setup.
• Smartphone Control via EMBER App: Manage schedules, temperature settings, and boost modes remotely from any smartphone or tablet.
• Sleek Touchscreen Interfaces: Backlit touch displays with intuitive controls, table stand or wall-mount placement, and integrated PIN lock safety.
• Energy-Saving Algorithms: Features Optimum Start and TPI (Time Proportional & Integral) control to eliminate temperature overshooting and reduce fuel consumption.
