  • Page 106 For the installer 15.3.3 CTC EcoZenith i550 Pro - Solar energy Solar panels (17) can be connected directly to the EcoZenith’s inbuilt solar coil (11). The solar coil is the finned type. The fluid is pumped from the coil by a speed controlled solar pump (G30).
  • Page 107 For the installer 15.3.4 CTC EcoZenith i550 Pro - Domestic hot water Figure 1 Shows how domestic hot water circulation can be connected to the EcoZenith. The domestic hot water is circulated by pump (G40). New domestic hot water from the finned coil is mixed in by the mixing valve (32), and cooled water is released down to the coil for reheating.
  • Page 108 For the installer 15.3.5 CTC EcoZenith i550 Pro - Wood boiler The upper and lower connections are used for connecting a wood boiler to the EcoZenith. This means that the flow from the wood boiler passes through the entire EcoZenith. The flue gas sensor (B8) signals to the EcoZenith’s control system that the wood is burning.
  • Page 109 For the installer 15.3.6 CTC EcoZenith i550 Pro - Storage tanks (buffer tanks) One or more storage tanks can be connected to increase the water volume; this is done most commonly in connection with wood or solar energy operation. The 3-way valve (Y40) is connected to the upper connection from both the EcoZenith’s upper and lower tanks and then to the top of the first...
  • Page 110 For the installer 15.3.7 CTC EcoZenith i550 Pro - External boiler An external boiler (oil, pellets, electric or gas) is connected to the EcoZenith’s upper tank connections. Circulation is undertaken by the pump (G44), which is controlled by the EcoZenith. The sensor (B17) senses the boiler temperature in the external boiler.
  • Page 111 For the installer 15.3.8 CTC EcoZenith i550 Pro - Pool A pool is connected to the EcoZenith’s lower tank. This means that the pool is heated by the same energy source as the radiator system prioritises, for example, heat pump or solar panel. One pump (G50/G51, at the top of the drawing) circulates radiator water from the upper connection on the EcoZenith’s lower tank (02) to the pool heat exchanger (14), on to...
