Kindly tell me which function or code would be used to stop the working of a water heating system, built in TRANSYS, for 3-4 months. The system will remain in working condition for the remaining months.
If you want to imitate case when system is off because of some abnormal situation (blackout, fault, human interruption etc.) I would recommend to do following. In TRNSYS 1-on & 0-off control function is used and controllers typically give 1 or 0 as an output signal. Create a txt external file with 0 for the off situation and 1 for all the rest simulation period. Link this file with TRNSYS and multiply values with output from controllers. This will give you normal operation with off period when you want.
