Input Configuration - Vector TCY-MT2-W01 Instruction Manual

Input configuration

Parameter Description
CP 18 Configuration of remote input (X1)
0 = Control Input
1 = Comfort/Economy Mode switch
2 = Comfort/OFF Mode switch
3 = Keycard switch function
4 = Output enable
CP 19 Activation delay (minutes):
The time the binary input needs to be open before Economy or
OFF mode is activated.
CP 20 Fixed set point for key card function in heating mode
CP 21 Fixed set point for key card function in cooling mode
CP 22 For TCY-MT2 only: Enable Auto changeover
CP 23 For TCY-MT2 only: Auto changeover limit heating
CP 24 For TCY-MT2 only: Auto changeover limit cooling
Configuring the function of the external input X1

The external input X1 may be configured for several functions:
CP18 = 0 External control input
CP18 = 1 Switching Economy and
Comfort modes
CP18 = 2 Switching Energy Hold
OFFand Comfort modes
CP18 = 3 Key card function
CP18 = 4 Output enable
Configuring auto changeover input X2 (TCY-MT2 only):

The auto changeover function automatically changes heating and cooling mode based on supply media
temperature or outdoor temperature. The difference between the two is in the values of the changeover limits
CP23 and CP24. See table below for recommended settings.
Heating and cooling may be as well changed by an open contact switched to signal ground. Note: all signal
ground levels of involved controllers must be the same in case more than one controller is switched.
Recommended settings for CP23 and CP24:

Change over mode
Supply media
Outside temperature
Dry contact: Heating if contact closed
Dry contact: Cooling if contact closed

Subject to alteration
The control input is provided by the external input. The internal input
will not be used.
Economy (unoccupied) and Comfort (occupied) modes are controlled
through an external contact by connecting X1 through a dry contact to
signal common. This function may be used together with key card
switches for hotels or motion detectors for offices.
Opening the external temperature input will force the unit into the OFF
operation mode. The operation mode cannot be overridden by using the
terminal. Connecting the binary input to GND returns control of the
operation mode to the terminal. This function may be used as window
contact to prevent loss of energy.
As with CP18 = 1, the key card function switches economy
(unoccupied) and comfort (occupied) modes. Instead of using the set
point shift, the set points in unoccupied mode are defined by parameter
CP20 and CP21.
This may be used for a dew point sensor input. Output will switch off if
contact opens.
