9. Operation and Maintenance
Once your new EcoZenith has been installed, you and your installer should
together check that the system is in perfect operating condition. Let the
installer show you where the switches, controls, fuses etc. are, so that
you know how the system works and how it should be maintained. Bleed
the radiators after around three days of operation and top up with water if
required.
CTC EcoZenith i555 Pro
The EcoZenith is prepared for connection to a CTC heat pump, wood boiler,
other additional boiler, solar energy, passive cooling, borehole charging
and pool. The EcoZenith operates fully automatically. The control system
turns on additional heat when needed, adapts to wood burning when this
occurs, switches to summer mode, etc. For a more detailed description of
how EcoZenith’s design and functions, refer to the "EcoZenith’s Function"
chapter.
Safety Valve for Tank and heating circuit
Check regularly that the valve is working properly by manually turning the
valve knob. Check that water is coming out of the safety valve discharge.
The overflow pipe outlet must always be open. Warning Hot water can drip
from the safety valve.
Draining the tank
The tank should be disconnected from the power source when it is being
drained. The drain valve is packaged separately and can be connected
directly onto one of the lower connections, if one is free, or to a low lying
pipe. When draining the whole system, the mixing valve should be fully
open, i.e. turned anticlockwise as far as it will go. Air must be supplied to the
closed system.
Operation Stop
The product is turned off with the safety switch. If there is a risk of the water
freezing, all the water should be drained from the tank and the heating
circuit. The DHW coils, which contain about eleven litres, are emptied by
feeding a hose all the way down the cold water connections and then
siphoning out the water.
Current monitor
The EcoZenith has a current monitor which measures current up to 100 A.
If the system is fitted with a current sensor, the property’s main fuses are
continuously monitored to ensure they are not overloaded. If this should
happen, electric stages are disconnected from the electric heater(s).
Mixing Valve
The mixing valve is operated automatically from the control system, so that
the correct temperature, irrespective of the season, reaches the heating
circuit. However, where a fault occurs, you can operate the valve yourself by
pulling out the knob on the motor and turning it anticlockwise to increase the
temperature or clockwise to reduce it.
! Remember to reset
the mixing valve to
automatic mode.
