Main Features Specific temperature control Less programming, lower cost Auto detection for external control sensor Key card or occupation sensor input. Specific solution for 2-pipe or 4-pipe applications VAV solution for –MT type Plug & Play for standard applications. No need to setup anything.
Plug & Play Auto detection of inputs The control signal will be taken automatically from the external sensor if a valid input signal is detected No need to program 11/19/2010 Intro TCY-MT, TCY-FT Slide 7...
Control Modes The temperature controller operates a heating or cooling device. Select the control logic with one parameter: CP11 defines the control mode 0 = Cooling mode: order preset with W01 1 = Heating only mode: order preset with W02 2 = 2-pipe mode: (Factory default for -2 products) 3 = 4-pipe mode: (Factory default for -4 products) This option is only available on -4 products.
