This function is used to transfer heat from the storage tank to the collector in order to avoid freezing of the heat transfer medium is some system types.

This system uses a solution of propylene glycol and water and is freeze resistant to -30 °F; therefore, this function is not necessary.

The recooling function is used to cool the tank when the maximum tank temperature (S MX) is exceeded, such as when the collector cooling function (OCX) is activated and the tank may reach 203 °F (emergency shut down of the tank).

When the collector is 5° cooler than the tank the pump will run to dump excess heat from the tank in the piping and at the solar collector until the tank is cooled to the maximum tank temperature setting.

The tube collector function is only needed for systems that use vacuum tube solar collectors.

This function is not necessary for this system.

A Heat quantity measurement is possible for this system in conjunction with the flow meter. In order for this function measure the heat gain of the system the optional temperature sensor 4 (return flow sensor) must be added and connected to the copper pipe between the coil outlet on the tank (marked “to pump”) and the solar pump station.

For OHQM to give an accurate reading the volume flow readable at the flowmeter (gal/min) must be adjusted in the channel FMAX.

For OHQM to give an accurate reading the type of heat transfer fluid type(antifreeze) must be set in the channel MEDT:

0:water

1:propylene glycol

2:ethylene glycol

3:Tyfocor ® LS / G – LS

Caution: for this system type only type 1: propylene glycol should be selected. Use of any other type of heat transfer fluid in this system may cause damage to the system or present a health hazard
