integrated dual-energy equipment Integrated dual-energy equipment features an emergency switch, which should be left in the Normal position unless the electronic controller on the heating system has been damaged. If the switch is in the Emergency position, the system will only operate in fuel mode. installed equipment All installed equipment, except for the meter, belongs to you. You are therefore responsible for checking its condition and having it maintained. Heat pump Dual-energy systems with a heat pump have special features. The right-sized heat pump can generally provide comfortable heat without the aid of another energy source until its balance point temperature is reached. Here is how a dual-energy system with an air-air heat pump normally operates. • When the outdoor temperature is above the balance point, the heat pump alone is sufficient for heating. • When the outdoor temperature drops to the balance point or lower, the heat pump is assisted by the other energy source. • When the outdoor temperature falls below the switchover temperature, the heat pump stops operating and the auxiliary energy source takes over all heating. Note: A heat pump doesn’t affect the way the dual-register meter works. The switchover temperature is still −12°C (or −15°C), even if the heat pump requires assistance before that temperature is reached. balanCe point A few degrees below freezing.

Your electricity bill You’ll continue to receive your electricity bill every two months, or every month if you’re on the Equalized Payments Plan. In winter, your bill may be slightly higher than it was before with Rate D. This is normal because, during very cold weather, your consumption is billed at a higher rate, even when your home is heated with fuel. Over a twelve-month period, however, you’ll save money. When the temperature is above the switchover point—and this is most of the time—your electricity consumption is billed at a lower rate. 10 11
