Applications
STemperature Control for
oRadiator, Floor heating, Cooling Ceilings
oStand alone VAV outlets for pressure
dependent control or in conjunction with
VAV actuators: pressure independent
control
oZone control for residential, offices, meeting
rooms, hotels or schools.
oFor 0-10V/2-10V or 24VAC 3-point
actuators

SThe control signal
will be taken
automatically from
the external sensor if
a valid input signal is
detected
SNo need to program

Control Modes
11/19/2010 Intro TCY-MT, TCY-FT Slide 8
SThe temperature controller operates a heating or
cooling device.
Select the control logic with one parameter:
SCP11 defines the control mode
S0 = Cooling mode: order preset with W01
S1 = Heating only mode: order preset with W02
S2 = 2-pipe mode: (Factory default for -2 products)
S3 = 4-pipe mode: (Factory default for -4 products)
This option is only available on -4 products.

VAV Function on TCY-MT
11/19/2010 Intro TCY-MT, TCY-FT Slide 9
Define individual min and max limits for
heating and cooling on the analog outputs
This is used to set min and max airflow on
linearized VAV actuators.

Manual Override
SActivate manual
positioning for
comissioning
SSet CP12 to ON to set
the outputs into
manual mode.
SOn -4 products: To
switch between heating
and cooling outputs,
change heat – cool
mode of controller

Heat-Cool Change
S2-pipe controllers need to change heating and
cooling mode. They can be defined with three
parameters: These options are available:
11/19/2010 Intro TCY-MT, TCY-FT Slide 12
Change by: CP22
Enable CP23 Heating CP24 Cooling
Key pad only OFF
Outdoor temperature ON 25°C 15°C
Supply media temperature ON 15°C 25°C
Open contact: Close = heating ON 25°C 15°C
Open contact: Close = cooling ON 15°C 25°C

Features on Ext Input
SAll products have at least one ext input. These
are the features:
oCP18 = 0: Auto detection mode. Use as control
input, if the controller detects a valid input signal.
oCP18 = 1: Occupation sensor: switch comfort –
standby mode
oCP18 = 2: Remote enable: Switch Comfort – OFF
oCP18 = 3: Key card mode: Fixed setpoints if contact
is open. Setpoints are fixed to CP20 in heating mode
and CP21 in cooling mode.
