VFMQ Storage Heater
Off-Peak Timing Control Options
VFMQ storage heaters are designed to store heat during the Off-Peak period when electricity is
less expensive. The accuracy of the timing controls is critical to cost effective operation.
PLEASE NOTE. Different electric utilities use various control methodologies. Please contact
your electric utility to understand their Off-Peak control procedure and if they offer an Off-Peak
timing device.
The most common alternatives:
• A utility-supplied control relay. Popular with Rural Electric Cooperatives.
• A utility-supplied dry contact on a meter. Standard for Nova Scotia.
• A timer. Standard in Ontario.
Automatic vs Manual Charge Control
Managing the amount of energy to store to meet the next day’s heating requirements can be
done automatically or manually.
1. Automatic Charge Control requires the Dimplex DCP2010 Charge Control Panel to estimate
how much heat to store to meet the next day’s heating needs. It does this by using
advanced algorithms based on temperature data and user preferences.
Automatic charge control is better:
• for sites with more than one heater.
• when low user involvement is desired.
• to individually control up to 4 additional circuit loads such as your water heater,
baseboard heaters in non-living areas or any other loads on their own circuit up to 30
Amps.
• at reducing the sizing of the storage heater in areas that offer mid-peak periods, due to
its intelligence for minimizing the use of more-expensive mid-peak power for the coldest
days.
2. Manual Charge Control allows the user to decide how much heat to store for the next day by
adjusting a knob on the side of the storage heater and:
• is less expensive, eliminating the need for the DCP2010 Charge Control Panel.
• is recommended for single heater installations.
• can be upgraded to use the DCP2010 automatic charge control system at a later time.
