TC903-3A4LA Schneider SpaceLogic Hotel Room Wall Thermostat
On/Off Valve LCD 240V White Frost Guard
Product Overview
The TC903-3A4LA is a stand-alone fan coil room thermostat from the Schneider Electric SpaceLogic TC900 range, supplied in white for four pipe applications. Designed to operate terminal units directly without any supervisory connection, this thermostat ensures reliable climate control regardless of network availability or building management system status.
Standalone operation ensures continuous room climate control during network outages, commissioning delays, or ownership changes.
The intuitive five-button interface with liquid crystal display provides clear visibility of temperature, mode, and fan speed settings. With three-speed fan output compatibility and built-in frost protection and economiser logic, this thermostat protects both terminal unit equipment and occupant comfort.

Commissioning involves parameter setup rather than programming. Critical settings include fan speed modes, setpoint limits to prevent extreme temperature settings, and appropriate changeover behavior for the terminal unit.
Four-pipe units require proper circuit activation decisions based on water temperature sensors
Wide voltage range (90-240V AC) accommodates both 110V and 230V systems
Optimal wall placement is essential - avoid locations near heat sources, lamps, or drafts
