Mode 3

This mode selection is for hydronic heating systems with

single or multiple heaters (maximum 4 heaters) in primary/

secondary piping configuration with or without Outdoor

Air Reset (S4) with indirect DHW on the heater loop (with

priority). See

Figure 21.

The system temperature is controlled by the Supply Sensor

(S3) whenever the indirect call for heat is

not active. The

DHW Supply Sensor (S5) determines the indirect call/tank

setpoint. During an indirect call for heat the heater firing

rate is determined by the water temperature at the Indirect

Supply Sensor (S6) and the Target Max setting when using

the Indirect DHW sensor (S5).
The Heater/Injection Pump (P1) runs during all heat calls

regardless of priority. The Indirect DHW Pump (P3) runs

during an indirect call for heat with no “Off” delay.

Figure 21.

Mode 3 - Single Heater with Indirect on Heater Loop Primary/Secondary Piping

The Heater/Injection Pump (P1) is delayed “Off” as user-

defined in the Heater menu and the System Pump (P2) is

delayed “Off” in the ADJUST menu.
The System Pump (P2) runs whenever the system is

enabled for heating and the outdoor air temperature

is lower than the warm weather shut down (WWSD)

temperature setting (if utilized) unless an indirect call for

heat is present.

NOTE:

A Tank Aquastat can be used in lieu of the Indirect

DHW Sensor (S5). See VERSA IC Manual (5000.72) for

additional details.
