WIRING AND COMMISSIONING INFORMATION FOR
SATCHWELL MICRONET MN650
CONTROLLERS
APPLICATION
Satchwell MicroNet MN650 Series Controllers are fully-programmable
controllers designed for roof top, unit ventilator, air handling unit (AHU)
and zone heating and cooling applications. These controllers feature
universal inputs (UIs), digital inputs (DIs), triac outputs for 24Vac loads,
analogue outputs (AOs) and support for one MN-Sx digital sensor. The
MN650 controller operates from an external 24Vac or 24Vdc supply.
By setting the controller’s jumper pins, any of the universal inputs may
be configured as an analogue, resistive, or dry (volt free) contact input.
MN650 controllers can operate standalone or be networked in a
MicroNet ARCNET
®
network or a Native Communications Protocol
(NCP) network. For any model of controller, a PC with VisiSat™
Configuration Tool software is necessary to download and modify
applications.
An optional Real-Time Clock card can be fitted, which maintains
controller time during a power failure. The RTC card contains a 3V,
125mAh Lithium cell which has a life of at least 5 years.
Networked controllers receive time updates automatically from a
MicroNet Manager Interface or Touch Screen time master.
A Satchwell MicroNet Touch Screen or LCD can be mounted onto the
controller, which allows a user to view and modify controller properties.
Please refer to the Touch Screen Engineering Data Sheet (DS
10.050A) or to the LCD Engineering Data Sheet (DS 10.060A).
The controller also features an onboard power capacitor, to preserve
RAM for a maximum of seven days.
