Single Room Manual Heating Gas Boiler Thermostat For HVAC Systems
S2305 is a manual single room thermostat for HVAC, radiator and boiler systems, operated with a slider rather than a menu. It measures from 0 C to 40 C in 0.1 C steps, holds a setpoint between 5 C and 35 C in 0.5 C steps, and drops into frost protection at +7 C when switched off. Backing it up is a 2 year warranty and an after sales package that can include onsite installation, training and inspection.
