Aug 01, 2011  A proven, reliable and accurate unit, the Economy 7 Quartz is easy to install and set, providing a tankful of hot water to start each day utilising Economy 7 off peak rate overnight electricity. The manual boost timer provides extra hot water in the day time - should it be needed. Box Contains. 1 x Programmer 1 x Instructions. Mar 02, 2015  The water only heats using the boost option. The timer itself seems to be working fine, I can hear it ticking and see it's moving round, the light comes on early in the morning which suggests that it should be heating the water, but after the timer light goes out the water is still freezing cold. The water only gets hot after boosting it.

Quartz E7 Water Heater Control Manual

Hi, I've recently moved into an apartment which has a hostmann economy 7 quartz water heater. Since moving in, it appears that I can't get the timer function to work properly. The water only heats using the boost option. The timer itself seems to be working fine, I can hear it ticking and see it's moving round, the light comes on early in the morning which suggests that it should be heating the water, but after the timer light goes out the water is still freezing cold. The water only gets hot after boosting it. Can anyone please recommend any solutions to what I can do to try and get the timer function to work and actually heat my water?
Thanks in advance
