The ST-300 is a mains voltage programmable digital thermostat with a large clear LCD display for domestic or commercial use. The ST-300 is designed to control heating zones which can be pre-setto temperatures via the programming or temporarily manually overridden to suit the end user’s requirements. The ST-300 can be used to call for heat, control zone valves, switch electric underfloor heating systems and connect to a UFH wiring centre with a high maximum switch loading of 16A. The ST-300 has a 5/2 week schedule, with 6 time periods per day and includes a Child Lock function for safety and to avoid tampering. It has a remote sensor terminal for accurate floor temperature control or can be used as an over temperature protection sensor which can be adjusted in the hidden advanced settings. The ST-300 includes anti-freeze protection which operates even in the off state and an adjustable maximum temperature setting to prevent overheating and energy wastage.
