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.

Automatic Charge Control Wiring DCP2010 Charge Control Panel Dimplex’s DCP2010 Automatic Charge Control Panel provides the intelligence for the system and: • can control up to 30 VFMQ storage heaters. • can control up to 4 additional 30 Amp loads including the existing water heater, baseboard heaters in non-living areas and any other loads on their own circuit. • the panel is supplied with an external temperature sensor with a 2m (6.5 ft) connection cable that can be extended to 30m (98 ft) by #16/2 wire.

Wiring the TS521W Wall Thermostat When wiring to the Dimplex TS521W wall thermostat, two additional fuses (F1 & F2) are required to protect the external wiring with a minimum rating of 240 volts and 15 Amps. • The fuses must be wired in-line from terminals 1 & 5 with fully-rated wire (#8 or #10). The stat can then be wired with #12 or #14 from the fuse block. • The 2 x fuse blocks can be installed within the VFMQ storage heater near the terminal blocks.

Wiring the RTEV99 Internal Thermostat As per the RTEV99 Instructions, fasten the sensor probe assembly by the supplied screws on the base next to the fan. There are four wires: • The white wire marked LE is wired into lower terminal block #7. • The white wire marked LH is wired into lower terminal block #10. • The two wires crimped together are wired to the lower terminal block #8 and jumpered to the upper terminal block #5 / N. • The brown wire marked L is pre-wired to a 2-pole terminal block at #12.

VFMQ Manual Charge Control Option To reduce the installation cost in homes that require only a single storage heater, the heater’s heat storage charging can be controlled manually eliminating the need for the DCP2010 automatic charge control panel. Every Dimplex storage heater has manual charge control functionality built in. This manual charge control option allows the homeowner to manually decide how much heat energy to store during the next Off-Peak period.

Option 1. Typical Control Wiring Solution with a Contactor in a Utility-Supplied Device Note: • Use a “normally open” contact if the Utility signal is an open contact for the Off-Peak periods. (Shown) • Use a “normally closed” contact if the Utility signal is a closed contact for Off-Peak periods.
PAGE 8
Option 2. Control Wiring Solution using a Low Voltage Dry Contact from a Utility-Supplied Device • • This method requires low voltage to be passed across a Utility-supplied contact. Used by Nova Scotia Power, the dry contact is part of their Time-Of-Day meter. The transformer is only needed to provide low voltage to the dry contact. Examples of components: • Marcus 12/240 to 12/24 AC transformer - MRCMO50A. • Schneider relay - TLPRPM21B7 and Schneider relay base - TLPRPZF2.
PAGE 9
Option 3 – Control Wiring Solution using a Timer • • • • • Used in lieu of a utility-supplied timing device. An example is Ontario where the Smart Meters do not include physical contacts to synchronize the system to. This solution requires an accurate timer programmed with the Utility's Off-Peak schedule. An example is the Intermatic ET1725C with 7 day programmability, battery backup and changes automatically for daylight savings time. The timing device must be rated for switching 240 volts.
