5100 Series Only

Static Heat Recovery Relay - Threshold for energizing the Static Heat Recovery relay.

Value

Description

0

0 Energizes relay during any hydronic "H" heat call. Primarily used to operate secondary loop pumps with the orange and white wires.

10 to 1200 before version 2.08

10 to 1600 in version 2.08 and later

The relay will energize when the average brick core temperature is greater than this value. Primarily used to operate the Static Heat Recovery Unit.

9100 Series Only

Static Heat Recovery Relay - Threshold for energizing the Static Heat Recovery relay.

Value

Description

0

0 Energizes relay during any hydronic "H" heat call. Primarily used to operate secondary loop pumps with the orange and white wires.

10 to 1600

The relay will energize when the average brick core temperature is greater than this value or receives a “G”, “Y” or “W” input. Primarily used to operate the Static Heat Recovery Unit.

 

Version 2.18 and Higher:

Start High Temperature Input Reduction - Used to set the temperature at which the maximum power allowed to the elements will begin to be limited by the SSR’s. The maximum power input will be limited proportionally between this value and the Maximum Core Temperature (L040) while still targeting the same maximum core temperature. This greatly reduces the maximum element temperature which improves the life of the heating elements. Reference L057 for additional information.
