19 sequence of operation ormal peration (ll dip switches in the off position) he control will scan all terminals looking for a call for heat from any thermostat. When a call for heat is detected the green LED for that zone will illuminate. he corresponding zone terminals 1 & 2 will be energized with 24 volts. he control will then wait for the zone valve end switch to close, a red LED will illuminate, indicating an open valve. nce the zone valve opens the primary pump is energized with 120 volts and the X-X contact will close. riority Chosen he control will scan all terminals looking for a call for heat from any thermostat. When a call for heat is detected on the priority zone the green LED for the priority zone will illuminate. he priority zone (zone 1) terminals 1 & 2 will be energized with 24 volts. he control will then wait for the priority zone valve end switch to close, a red LED will illuminate indicating the valve has opened. nce the zone valve opens the primary pump is energized with 120 volts and the X-X contact will close. While the priority zone is calling for heat any call for heat on zones 2 and above will be ignored until the priority zone is satisfied or the priority timer has elapsed. (See riority imer in this manual for a more detailed explanation.) f call for heat is detected on terminals 2 or above when the priority zone is not calling the control will operate as outlined above. 19

20 sequence of operation riority ump Chosen n order to use the priority pump feature both the zone valve/pump and priority dip switch must be in the on position. he control will scan all terminals looking for a call for heat from any thermostat. When a call for heat is detected on the priority zone the green LED for the priority zone will illuminate. he jumper on terminals 3 & 4 of the priority zone will result in the end switch being automatically closed. he priority pump is energized with 120 volts and the X-X contact will close. While the priority zone is calling for heat any call for heat on zones 2 and above will be ignored until the priority zone is satisfied or the priority timer has elapsed. (See riority imer in this manual for a more detailed explanation.) f call for heat is detected on terminals 2 or above when the priority zone is not calling the control will operate as outlined above. Z-ZC he control will scan all terminals looking for a call for heat from any thermostat. When a call for heat is detected the green LED for that zone will illuminate. he corresponding zone terminals 1 & 2 will be energized with 24 volts. he control will then wait to for the zone valve end switch to close; a red LED will illuminate indicating an open valve. he X-X terminal will be closed. he control will wait for a signal back from the Z- ZC terminals on the boiler aquastat. nce the signal is received the ZC n light will illuminate. 20

21 sequence of operation he primary pump will be energized with 120 volts. D-2 Chosen he control will scan all terminals looking for a call for heat from any thermostat. When a call for heat is detected the green LED for that zone will illuminate. he corresponding zone terminals 1 & 2 will be energized with 24 volts. he control will then wait for the zone valve end switch to close; a red LED will illuminate indicating an open valve. fter the end switch has closed the Z-C control will wait to receive a signal from the D-2. lease see the separate D-2 manual for the D-2 sequence of operation. nce the D-2 sends a signal back to the Z- C control the primary pump is energized with 120 volts and the X-X contact will close. riority imer When the priority zone has called for heat for 30 minutes, the priority and non-priority zones are allowed to call for heat together for an additional 30 minutes. fter the second 30 minute period ends, the control will switch back to priority only mode. his pattern is repeated until the priority zone is satisfied. ump nactive imer (exercises pumps if off for more than 24 hours) f either the primary or priority pump is off for more than 24 hours, both pumps are turned on for 5 seconds and then turned off. f either pump is turned on, the timer is reset. : he Z-ZC and D-2 selection switches should not both be in the n position at the same time. 21

22 Zone StaGing Zone Staging is a feature that is unique to the Z-6C control. When the Z-6C senses a power demand that exceeds the capabilities of the 75V transformers, the control will energize one zone at a time until all calling zone valves are opened. lease note that riority/zone 1 is not affected by Zone Staging and is permitted to open at any time. Z-Cp control expansion Following the instructions below, up to two (2) Z-C controls can be wired together. sing two Z-6C controls, this allows a maximum of ten zones plus a priority zone to be installed in a system.!
