SECURE HO E7Q Water Heater Controller Instruction Manual
The Economy 7 Quartz is an Electro-mechanical water heating control, which can be set to take advantage of cheap night-rate electricity, so that there is a tank of hot water available for the morning.
INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE IET WIRING REGULATIONS.
WARNING : ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION
The clock
The 24 Hour dial rotates once each day. It should be set so that the time line
is against the ‘WINTER TIME’ line in Winter or the ‘SUMMER TIME’ line during
British Summer Time. Adjust the clock by turning the dial clockwise.
A battery reserve will keep the clock running even if the mains supply is
interrupted for up to 6 days.
Water heater switch
In the WATER HEATER OFF position the heaters remain OFF but the clock will run and the stand-by battery will remain charged. In the TIMED position the over- night immersion heater will be switched ON and OFF at the pre-set times.
Boost timer
When extra Hot water is required during the day the Boost Timer can be used. Where two immersion elements are fitted in the tank the Boost Timer switches on the upper heater only.
Turn the knob anti-clockwise to the ‘START’ position to operate the Boost Timer. The Boost period can be limited by turning the knob anti-clockwise to one of the intermediate positions if less than the maximum Boost period is required. The immersion heater will be switched OFF after the selected period, or when the temperature of the water reaches the thermostat setting. If required, further Boost periods can be selected. The electricity used will be at the appropriate day tariff rate.
Neon indicators
The TIMED neon will illuminate when the immersion heater is activated
The BOOSTneon will illuminate when the Boost timer is in use.
OFF-PEAK heating period
Your Installer would have already set the Off-Peak heating time to suit local switching times as supplied by your Regional Electricity Company.
