Interface Selection ((); Dhw Cut-In Temperature (B); Fan Speed At Dhw Full Load (C); Forced Part Load Time After Start (Htg Only - G) - REMEHA Quinta 115 Technical Information

6.6.6 Interface selection (()

Adjustable 00 or 01.
This value sets the control option.
01 for standard 0 -10 V external control.
00 for the Honeywell Chronotherm option.

6.6.7 DHW cut-in temperature (B)

Adjustable from 01 to 20 °C (8 steps, see Table 09).
DHW demand
With sensor:
- The DHW demand is satisfied when the DHW temperature equals the DHW set
point temp (parameter #) + 5°C.
- The DHW cut-in temperature sets the dT below this end point for DHW demand.
Cut-in temperature = DHW set point (55) + 5 - parameter B (5), i.e. 55 + 5 - 5 = 55°C.
With thermostat:
- The thermostat determines the DHW demand.
Boiler modulation during continuing DHW demand
Sensor and thermostat:
- The boiler will modulate when the flow temp equals the DHW set point + DHW
control stop set point (parameter I) i.e. 55+20 = 75.
- The boiler carries out a control stop at a flow temp of 80°C (modulation point +
5°C), the display initally shows 980, reducing to 975.
- The DHW cut-in temperature sets the below this control stop.
Cut-in temperature = DHW set point (55) + DHW control stop set point (parameter I)
+ 5 - parameter B (5), i.e. 55 +20 + 5 - 5 = 75

6.6.8 Fan Speed at DHW full load (C)

Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm).
This value sets the maximum output of the boiler.
Parameters D - E - and F are factory set and must not be changed

6.6.9 Forced part load time after start (HTG only - G)

Adjustable from 00 - 15 min.
This value sets the period of time the boiler will stay on part load at start up during
which time the flow temp is limited by part load temp set point (parameter $)
Changing the factory default should only be carried out on advice from the service
engineer.
NOTE: When using an external analog (0 -10 V) or 2 wire modulation input, the factory
default 03should be changed to 00.
