2.7 Maintenance benets
2.7.1 Complete operation display by LCD user’s interface
The LCD user’s interface display menu allows to check all the important parameters and status of the unit in any moment.
Most of these variables are the same ones that can be consulted by 7-segment, taking information from the outdoor unit.
• System operation: Heating mode, DHW, SWP, ...
• Unit status: Display of more specic parameters (indoor/outdoor expansion valve opening, inverter operation frequen-
cy, defrosting, ...).
• Actual temperature: A large serie of operation temperatures (water inlet/outlet temperature, room temperature of cir-
cuits 1 and 2, outdoor ambient temperature, gas/liquid temperature, ...).
• Set-point: The set-point temperatures will be displayed in order to allow to the user/installer compare the actual and
setting temperatures in any moment (room temperature and OTC supply temperature set-point of circuits 1 and 2,
water temperature setting, ...).
Additionally, a large variety of parameters can be set by the installer (most of them also by the user) helping with the service
works and resulting in a very dynamic system work.
2.7.2 Front access to the electrical box
By removing the indoor unit front cover and the electrical box cover it is possible to have a frontal access to the electrical
box components (terminal boards 1 and 2, transformer, etc.), allowing an easy service work.
