OD RESET MAX
1. OD RESET MAX means the outdoor temperature at which the
target temperature reaches its minimum (SUPPLY MIN).
2. In the examples of Figure 1, this occurs at 70 °F (the factory
default).
OD RESET MIN
1. OD RESET MIN means the outdoor temperature at which the
target temperature reaches its maximum value (SUPPLY MAX).
2. In the examples of Figure 1, this occurs at 0°F outside (the factory
default setting).
3. OD RESET MIN should equal the ODT (outdoor design tem-
perature) for the installation's location.
Remote target operation (0–10VDC input)
1. This function allows a remote analog input to regulate the supply
temperature for control operation/modulation. This can be done
for any priority, including network and local priorities for multiple
boiler networks.
2. The settings discussed below are accessed in the priority menu
for the applicable system. For detailed explanations of the priority
menus, see Figure 31, page 52.
3. See Figure 2 for an explanation of target temperature vs voltage
when using remote target operation.
4. In the priority menu for the applicable system, select 0-10V for
the TARGET ADJUST setting.
5. In the same priority menu, select the VOLTS FOR MIN and
VOLTS FOR MAX values. VOLTS FOR MIN sets the voltage
value for the desired minimum supply temperature. VOLTS FOR
MAX sets the voltage value for the desired maximum supply
temperature.
Remote modulation operation
(0–10VDC input) — Single boilers only
Using an external multiple boiler controller
modulation using an external controller only works with
each boiler set up as a SINGLE boiler in the SlimFit
Control setup.
1. Use this option for single boilers only. To use 0–10VDC for remote
modulation, go to Contractor Menu -> Assign Inputs. Then change
Input 1's source to 0–10V. The priority that is assigned to Input 1
cannot not be used by any other Input.
2. The boiler comes on at 0.9VDC and turns off at 0.8VDC. 2 VDC
= 20% input. 10 VDC = 100% input. These voltage settings are
not adjustable.
