1. QUICK START-UP GUIDE

This document contains summary information for the machine to start. Detailed recommendations are contained in the Maintenance Manual attachment
that we invite you to consult.
Contact ON/OFF (7/8) : Completely switches the machine on and off (it does not affect the consent circulator control L-K). The unit is equipped with a
closed ON/OFF contact from an electrical jumper. Should a remote ON/OFF selector be installed, the electrical jumper between 7/8 must be removed
and the remote control must be connected. In the event of KCTR installation, the ON/OFF contact must be closed from an electrical jumper.
Pump P1 Input (L-K): activates the internal circulator required to operate without KCTR. It can be used as a control to activate the machine if a room
thermostat is used. If input (L-K) is closed from the electrical jumper, the circulator on the machine will always be on, even after executing Off from KCTR.
Work temperature Set Point: The machine is set to work with set point 1, meaning the one regarding the radiant applications (low temperature). Should
the unit be applied to a fan-coil (high pressure) application system, Set Point 2 (13/14) contact must be closed. For mixed systems with radiant terminals
(low temperature) and fan-coil terminals (high temperature), Set Point 2 must be activated by closing contact (13/14). However, a mixing valve must be
used in order to prevent very hot or very cold water from being sent to the radiant terminals.
Heat or chiller pump mode: changing the mode of operation can be done either via USER INTERFACE (and KCTR if installed) (par 101 = 0), or by
using external contact terminals 11/12 (par 101 = 101 = 0 or 1).
DHW Production: It can be executed by means of a temperature probe connected to the end of the terminal (5/6) or a thermostat contact between
terminals (5/6). The unit must be set to operate with the probe or thermostat. For correct installation, refer to the relevant paragraph in this manual.
