158A
Touch Pilot control supplied with a 7 inch colour touch screen user interface
Leak detection
159
0-10 V signal to report any refrigerant leakage in
the unit directly on the controlller ( the leak detector
itself must be supplied by the customer )
Compliance with Swiss regulations
197 Additional tests on the water heat exchangers : supply ( additional of PED documents ) supplementary certificates and test certifications
Simple installation : for applications with cold 254-1762 water at condenser inlet ( ex . ground-source , groundwater-source , superficial water-source applications ) the signal permits to control a 2 or 3-way valve to maintain condenser water temperature ( and so condensing pressure ) at acceptable values
Extended remote control capabilities ( Set-point 254-1762 reset , ice storage end , demand limits , boiler on / off command ...)
Enhanced ease of use 254-1762

User safety : this contact can be used for any
control possibilities :
customer safety loop ; opening of the contact

Room temperature : permits set-point reset based on the building indoor air temperature ( with Carrier thermostat )
Set point reset : ensures reset of the cooling set-point based on a 4 – 20 mA or 0 – 10 V signal
Demand limit : permits limitation of the maximum chiller power or current based on a 0 – 10 V signal
Demand limit 1 and 2 : closing of these contacts limits the maximum chiller power or current to two predefined values

generates a specific alarm
Ice storage end : when ice storage has finished , this input permits return to the second set-point
( unoccupied mode )
Time schedule override : closing of this contact cancels the time schedule effects
Out of service : this signal indicates that the chiller is completely out of service
Chiller capacity : this analogue output ( 0 – 10 V ) gives an immediate indication of the chiller capacity
