• The MC Elite does not source any power to any of its output relays. When connecting the output to a pump, an external
power source must supply the pump or its starter with power. Wire the system output (Yellow wires) so that it make or
break the hot leg.
• Heat-Timer DOES NOT recommend sharing the power source to the control with any pumps or heavy electric equipment.
• Heat-Timer Corp. is aware that each installation is unique. Thus, Heat-Timer Corp. is not responsible for any installation
related to any electrical or plumbing diagram generated by Heat-Timer Corp. The provided illustrations are to demonstrate
Heat-Timer Corp.'s control operating concept only.
