Grant GES264 sequence controller

Heating controls hugely affect system performance and efficiency. The correct control system not only makes it easier to maintain a more comfortable temperature within the home, but it keeps heating bills and carbon emissions down by using less fuel.

Features & benefits

  • *5 year guarantee (subject to T&C's)
  • The Grant 264 sequence controller is designed to manage from 2 to 4 heat sources. These may include renewable technologies such as air source heat pumps and wood pellet boilers or alternatively oil/gas boilers.
  • The controller is able to cope with a mix of fuels all at the same time. This is achieved by using a common flow sensor and using the heat sources installed to satisfy the demand.
  • When controlling up to 4 appliances the controller will record the time run for every heat source/boiler and rotate the firing sequence to provide an equal burn time for all units. This will ensure that all appliances share the load throughout the year.
  • When firing takes place each unit will only run when required, depending on the load placed on the system. This ensures maximum efficiency and prevents unnecessary firing and wasted energy.
  • The water temperature may be weather compensated and used with or without hot water priority, depending on the pipework layout, pumps and motorised valve set up.
  • Depending on the system design and layout it is possible to include pump overrun.
  • Primary and hot water pumps can also be controlled by the controller. When used in conjunction with a buffer/thermal store the weather compensation facility will be disabled as the store would be kept at a constant temperature.
  • Reduces heating bills
