HVAC Temperature Control

Temperature switches in HVAC systems are typically mechanical controls that operate based on physics principles. Unlike electronic controllers, which rely on inputs & outputs to communicate with HVAC equipment, capillary switches react directly to environmental changes, triggering equipment adjustments in response.

Many HVAC systems prefer mechanical temperature switches because their failure modes are limited compared to electronic controls, ensuring greater reliability. For more information on how capillary switches are used for HVAC temperature control, explore the articles below.

QUALITY AMBIENT COMPENSATION

Our capillary thermostats feature ambient compensation to offset temperature differentials, ensuring greater accuracy as environmental conditions change. This technology helps maintain reliable temperature control, even in fluctuating surroundings, making our thermostat controls ideal for dynamic applications.
