FLOW TEMP. CONTROLLER [MAIN] (Cased) PAC-IF071B-E PAC-IF072B-E PAC-IF073B-E FLOW TEMP. CONTROLLER [SUB] (Cased) PAC-SIF051B-E INSTALLATION MANUAL FOR INSTALLER English For safe and correct use, read this manual thoroughly before installing the FTC unit.
“FTC (Sub)” is the abbreviation of “Flow Temperature Controller [Sub]”, which is described as “FTC (Sub)” in this manual. In this manual, “FTC” that is not followed by “(Main)” or “(Sub)” means “FTC (Main and Sub)”. Mitsubishi Electric is not responsible for the failure of locally supplied parts. 1. Safety precautions FOR INSTALLER Before installing the FTC unit, make sure you read all the “Safety pre-...

5. Dip Switch setting 5.5 Emergency mode (Heater only operation) The emergency mode is available when a failure on the outdoor unit of the heat pump or a communication error occurs. This mode uses booster heater or immersion heater as a heat source and automatically controls between the DHW mode and the heating mode. When the system is not incorporated with heater, the emergency mode is not available.
6. Before test run 6.1. Check After completing installation and the wiring and piping of the local application and outdoor units, check for refrigerant leakage, looseness in the power supply or control wir- ing, wrong polarity, and power cable is securely connected. Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is at least 1.0MΩ.
