Cascade Control - Lochinvar EcoForce EF80 Installation, Commissioning, User And Maintenance Instructions

C C
ASCADE ONTROL
Before commissioning a cascade installation, a number of parameters have to be adjusted.
These parameters can be programmed on the unit itself, without the use of a computer.
Changes in parameter may only be carried out by a skilled commissioning/service engineer, who has had specific
training for setting up the EcoForce water heater. They will be able to check whether the installation operates
correctly after the parameter change has been done
For programming all parameters of the water heaters, an interface cable for connecting the laptop to the water heater control and a laptop
with the appropriate software is required. Contact Lochinvar Technical support for further details. This software is used for programming but
also shows all measured temperatures and cascade behaviour during operation and service/fault history.
14.3.1 Parameter settings for cascade set-ups
Before programming the cascaded water heaters, make sure that all water heaters are connected (wire) with each other. Use connection 17
and 18 of each water heater.
Do not alternate these connections, so always connect 17 to 17 and 18 to 18.
After connection every water heater must be programmed. This can be done at the control panel. Press the [MENU] button and select the
[PARAMETER] menu. See graphics below.
