What temperature range does the 3100 Series thermostat support?

The 3100 Series hermetic thermostat has an operating temperature range of -29°C to 260°C (-20°F to 500°F) and an environmental exposure range of -62°C to 288°C (-80°F to 550°F). (Page 5)

What is the warranty policy for Honeywell thermostats?

Honeywell warrants goods of its manufacture as being free of defective materials and faulty workmanship. If warranted goods are returned to Honeywell during the period of coverage, Honeywell will repair or replace, at its option, without charge those items it finds defective. The standard product warranty applies unless agreed to otherwise in writing—consult your order acknowledgement or local sales office for specific warranty details. (Page 9)

Which thermostat series would be best for a low-voltage HVAC application?

For low-voltage HVAC applications, the 2450CMG Series, 2450RCG Series, 2450RG Series, 2455RG Series, or 3106 Series would be suitable options. These series feature gold alloy contacts designed specifically for low voltage applications and are factory calibrated for HVAC use. (Pages 2-8)

What are the different types of Honeywell thermostat series available?

Honeywell offers two main categories of thermostats: Commercial Thermostats (including the 2450 and 2455 series) and Precision Thermostats (including the 3000, 3100, 3150, 3153, 3156, and 3200 series). Commercial thermostats are designed for applications like HVAC, appliances, and office equipment, while precision thermostats are built for high-end industrial, aerospace, and critical commercial applications requiring tight tolerances and environmental specifications. (Pages 1-8)

What is the operating temperature range for the 2450A Series thermostat?

The 2450A Series thermostat has an operating temperature range of 47°C to 107°C (117°F to 225°F) and an environmental exposure range of 0°C to 150°C (32°F to 302°F). (Page 2)

Which thermostat series is suitable for aerospace and military applications?

The 3200 Series thermostat is NASA certified and space qualified, designed specifically to meet or exceed military and aerospace specifications for spaceflight use, including temperature stability, shock, vibration and cleanliness requirements. The 3000 Series is also suitable for military applications due to its all-welded, hermetically-sealed stainless steel construction. (Page 8)
