Re: [TRNSYS-users] On off time calculator type 980



Hi,
 
I found this sometime ago... It could be useful for you.

You could integrate the control signal to the pump (should be 0 to 1)
or build your own simple counter using an equation and an integrator,
such as type 24, based on some output value from the pump. For
example:

gt(pump_flow_rate,0) * timestep --> integrator

Type 24 may already account for the time step, you will have to check.

Cheers,
