High-limit safety: Engineered with a 650 PSIG trip point to immediately interrupt the control circuit upon sensing excessive head pressure

the capacitor is typically integrated or supplied with the unit to ensure the 120v motor starts reliably under load

ensuring reliable performance without sticking or freezing even in corrosive water conditions

Can I use this TXV on a 3-ton or 4-ton system

Proper nitrogen purging and heat management are essential during installation to prevent carbon buildup inside the 3/8" line

Siemens Building Technology 134-1504 Thermostat 323080-701 High-limit safety: Engineered with aThe Siemens Building Technology 134 1504 is a heavy duty, 4 wire 2 circuit electric low temperature detection thermostat designed to protect hydronic coils and heat exchangers from localized freezing. This 15 55F range controller features a DPST switch action and a 20 foot copper capillary element, ensuring that if any one foot section of the bulb senses temperatures below the manual reset setpoint, the circuit trips to shut down fans or close
