Digital Single Stage 1 Heat 1 Cool Weekly Programmable 24V HCAC System Air Conditioner Thermostat for Home
STN605 is the single stage member of the STN600 platform, controlling 1 heat and 1 cool on 24V systems. Like STN615 it can be set to 7 day, 5/1/1 or non-programmable, which lets one product cover hotel, office and institutional specifications. Sensing runs 32 F to 99 F (1 C to 40 C) with a setpoint range of 44 F to 90 F (7 C to 32 C) and accuracy of +/-1 C at 20 C.
